How Much Horsepower Does a Deleted 6.7 Powerstroke Have?

Struggling with low power in your Ford 6.7 Powerstroke on tough hauls? We see it all the time and know it hurts performance and fuel use. A delete and tune can fix that fast.

How much horsepower does a deleted 6.7 Powerstroke have? A deleted and tuned 6.7L Powerstroke typically makes 450 to 600+ horsepower at the crank. The hardware removal adds little power by itself. Horsepower varies depending on tune level and additional parts installed.

This guide explains real dyno numbers and torque gains, and reliability factors on the Ford 6.7 platform. You will also learn what affects power and long-term reliability.

What Does "Deleted 6.7 Powerstroke" Actually Mean?

Are emissions dragging down your truck's power? We know it causes extra heat and a slow response. A deleted 6.7 Powerstroke means removing factory emissions parts and adding tuning. This alters the performance and operating characteristics of the engine.

Deleted means removing or bypassing the DPF, EGR, and DEF SCR systems. The truck needs a delete tune to stop limp mode. This tune changes fueling, timing, and boost. It is for off-road or competition use only and is often illegal on public roads.

Components Involved

The major components that are typically involved in a 6.7 Powerstroke delete kit would include:

• Diesel Particulate Filter (DPF)
• Exhaust Gas Recirculation (EGR) system
• Diesel Exhaust Fluid (DEF or SCR) system

These parts control emissions but also restrict airflow and efficiency.

The diesel particulate filter catches soot in the exhaust. The exhaust gas recirculation system sends some exhaust back into the intake. The DEF and SCR setup uses fluid to cut emissions. Removing or bypassing these cuts backpressure in the exhaust. The turbo spools faster as a result.

The Necessity of Tuning

You cannot simply pull out a deleted 6.7 PowerStroke and use it without tuning the truck. Since the truck computer expects those parts to work, without a tune, the truck goes into limp mode and limits power to protect itself.

It will trigger a check engine light(s) due to not being tuned. The delete tune tells the ECU to ignore the missing parts. It adjusts fuel delivery for more power. It changes injection timing and adds boost where needed.

We once had a customer truck that would not drive over 30 mph until tuned. The tune also lets the engine run cleaner and stronger without the emissions loop. A good tuner loads the right file, and the truck wakes up.

A 6.7 Powerstroke delete or tune kit allows you to change the following components:

• Fuel Delivery
• Timing
• Turbo Boost

This is where the most power is gained, not from the deletion of parts alone.

Legal Disclaimer

In many areas, it is against the law to delete emissions components. The U.S. Clean Air Act makes it illegal on public roads. Usually, it is only permissible for vehicles that are strictly used for off-road or racing.

Always check with your local authorities to verify your area's laws. We tell every owner this is for off-road tracks or competition only. Many shops will not install on street trucks for this reason.

How Much Horsepower Does a Deleted and Tuned 6.7 Powerstroke Make?

A deleted and tuned 6.7 Powerstroke can produce significant power gains. Curious about the exact power numbers after a delete? We get this question every week, and we know owners want clear facts. The final power output depends on the tune quality, engine modification, and supporting modifications.

A deleted and tuned 6.7L Powerstroke makes 450 to 600+ horsepower at the crank. Stock sits at 400 to 475 hp, depending on the model year. Mild tunes add 50 to 100 hp while hot tunes add 100 to 200 hp or more.

Typical Crank Horsepower Range

A turbocharged, removed, and tuned 6.7 Powerstroke truck produces between 450 and 600 or more (up to 750 (+/-) at the crank), depending on the combination of the tune and the engine mods.

Stock 6.7 Powerstroke engines produce approximately 400 to 475 crank hp from the factory, depending on the vehicle manufacturer. Real-world deleted and tuned 6.7 powerstroke hp (Wheel horsepower) is about 10%-20% lower than crank numbers due to the drivetrain loss of power.

Performance Tiers and Gains

A basic DPF and EGR delete alone adds only 10 to 15 hp. The tune is what unlocks the rest.

Different tuning levels have different outcomes:

Mild / Tow Tuning (50-80 HP Increase)

• Best for everyday driving and towing with better MPG
• Adds approximately 100-150 lb-ft torque

Aggressive / Hot tuning (100-150+ HP Increase)

• Goal of maximum performance
• May exceed up to a 200-300 lb-ft torque increase
• May require supporting upgrades for reliability, like intake exhaust and airflow upgrades
• Some hot setups go over 150 hp at the wheels but put more stress on the drivetrain

Comparison Table: Estimated Power Gains

Setup	Estimated Crank HP	Estimated RWHP	Typical Torque Gain
Stock	400–475 HP	330–350 HP	Baseline
DPF/EGR Delete Only	+10–15 HP	Minimal change	+25–35 lb-ft
Delete + Mild Tune	+50–100 HP	400–430 HP	+100–150 lb-ft
Delete + Hot Tune	+100–200 HP	450–500+ HP	+200–300+ lb-ft

We built this table from real shop data and owner reports. It shows why the tune matters more than the delete hardware. Mild tunes keep the truck safe for work. Hot tunes chase peak numbers but need extra cooling and upgrades.

In our experience, trucks with mild tunes stay strong for years while hot ones need careful watching. The numbers help owners pick the right level for their use.

What Do Real-World Dyno Results Show for a Deleted 6.7 Powerstroke?

We test trucks often and know numbers tell the true story. The best way to understand how much power you can put to the ground is to read the dyno numbers themselves. While crank horsepower is measured from the crankshaft, it is always higher than what is delivered due to drivetrain losses.

Real dyno tests show a deleted and tuned 6.7 making big jumps. A stock 2019 F-250 hits about 340 RWHP. Mild tune adds 50 plus RWHP. Hot tune nearly doubles torque gains over stock. Drivetrain loss means crank hp looks higher than wheel numbers.

Understanding Drivetrain Loss

Based on the setup, trucks lose 10 to 20 percent of power through the transmission and axles. A truck with 500 hp at the crankshaft generally produces 420 to 450 hp at the rear wheels on a dyno.

Dynovox Case Study (2019 F-250)

The same vehicle (2019 F-250) is tested in three stages under the same dyno conditions.

• Stock: Approximately 340 RWHP
• Mild Tune + full deleted: Additional 50 RWHP of power gain
• Hot Tune + full deleted: Higher gains, with torque nearly doubling compared to stock.

This provides evidence of how drastic an effect tuning can have on actual power output. The truck pulled harder from low rpm and felt quicker on the road. Also check DYNO RESULTS-independent test 2017 6.7 engine on ford forum.

Why Dyno Numbers Vary

Results generated on roller dynos for RWHP numbers are not always the same due to a variety of factors, including:

• Dyno type and calibration
• Tire size and gearing
• Elevation and air density
• Weather and temperature variation

Each of these variables affects horsepower and torque result measurements.

Different dynos read a bit high or low. Bigger tires add rolling resistance. High elevation cuts air density. Hot weather hurts power, too. We always test in the same conditions for fair comparisons before and after numbers.

Owners should expect similar gains but plan for real-world variables. We tell customers to focus on how the truck drives more than the exact dyno sheet. The delete and tune still deliver clear improvements in response and pull.

Does Deleting a 6.7 Powerstroke Add Horsepower by Itself?

Simply removing a part results in a small increase of 5–15HP and possibly has some minor torque gains. However, most improvements in power are the result of tuning rather than removing the part itself.

Deleting hardware alone adds only 5 to 15 hp and modest torque. Reduced exhaust restriction helps the turbo spool faster. Better combustion from no EGR adds a bit more. The tune drives the 50 to 150+ hp jump.

How Power is Gained

Less Restriction

By removing the DPF, you reduce the back pressure in the exhaust. This allows the turbo to spool more quickly (typically anywhere from 15–20% faster).

Improved Combustion

The EGR system recirculates exhaust gases back into the intake. Removing this feature decreases the soot level in the air charge and aids in sustaining cleaner combustion temperature. These changes give small gains on their own.

The Tune (Main Factor)

Tuning adjusts fuel rates, adjust timing, and boost levels for more combustion energy.

We tested trucks with deleted parts but no tune. They gained 10 to 15 hp at best and still felt restricted. Add the tune, and the same truck jumped 80 hp or more. The hardware sets the stage, but the software unlocks the potential.

We always pair deletes with proper tuning. It prevents codes and gives safe power. Owners who skip the tune waste money and risk engine issues. The combo of delete plus tune delivers the full benefit every time.

How Much Torque Does a Deleted 6.7 Powerstroke Make?

Looking for massive low-end pull after a delete? We know torque makes towing and daily driving better.

Stronger tunes often push the deleted 6.7 over the 1,000 lb-ft mark. You get improved towing response and less turbo lag. Low-end acceleration feels immediate and strong.

The 1,000 lb-ft Milestone

A deleted and tuned 6.7 Powerstroke produces 1,000 lb-ft of torque. Higher performance tuning and the right supporting mods are needed to achieve this torque level.

The stock factory output of torque is far less than this amount, indicating a substantial torque gain. Torque increase is much influenced by the level of final tune and its calibration.

Mild tunes give 100 to 150 lb-ft extra and keep things smooth for work. Hot tunes chase the 1,000 lb-ft goal but need supporting parts. We recommend matching the torque to your truck's use.

Too much torque without upgrades can stress the drivetrain. The right tune gives usable torque that lasts.

Driving Impact

The ability to produce higher torque offers numerous benefits for daily driving, including:

• Towing: A truck with high torque can tow more easily and with less work.
• Turbo Lag: A truck with high torque has much less turbo lag due to higher exhaust flow and better tuning to increase spool time.
• Lower-End Acceleration: A truck with high torque provides much better throttle response when the pedal is pressed.

Many owners look for reasons to install delete and tune setups for 6.7 Powerstroke, primarily to increase torque for heavy use of the truck (like towing).

We towed heavy loads with tuned trucks and noticed the difference every trip. The engine stays in its power band longer.

Reliability, Supporting Mods, Drivability, and Lifespan

Worried about reliability after you delete and tune? We tune these trucks daily and know how to keep them strong for high miles. Supporting mods makes the difference.

Hot tunes over 150 hp need an upgraded turbo transmission and cooling for reliability. The 6R140 transmission holds up well with proper tuning. Stay with 50 to 75 hp tow tunes for daily work to balance EGTs and longevity.

If you delete the 6.7 Powerstroke engine from your truck, it can still be reliable as long as you have the proper tuning, maintenance, and supporting mods. The reliability of your truck relies more upon how you run the truck than the delete itself.

Many owners reach 200,000 plus miles on deleted trucks. Maintenance and smart tuning matter most. Increased power adds stress to the pistons, rods, turbo, and fuel system.

Supporting Mods for High Power

High-performance engines typically have hot tunes capable of producing over 150 additional deleted 6.7 powerstroke hp.

To help maintain reliability in situations like this, supporting upgrades helps maintain reliability in these ways:

• Upgraded cooling systems can help support and manage the higher heat being produced by the engine.
• Stronger turbochargers and bigger injectors can be used in setups producing maximum output.
• Transmission tuning can provide smoother shifts and ensure proper line pressure. The 6R140 transmission is very durable. However, it might require tuning to prevent slipping under extremely high torque loads.

Safe Power Levels

For towing and everyday driving, using a 50–75 HP tow tune is usually the best option.

This produces:

• Lower exhaust gas temperatures
• Stable engine stress levels
• Balanced performance

Typically, this setup is highly preferred for long-term use.

We run tow tunes on fleet trucks and see great durability.

Longevity Expectations

Several deleted 6.7 Powerstroke trucks can reach over 200,000 miles if properly maintained.

However, how long these trucks last relies heavily on:

• Routine maintenance
• Mild tuning
• Limited frequent use of the wide-open throttle

The increased horsepower places more strain on the following components:

• Pistons and rods
• Turbocharger
• Fuel system
• Transmission

Bottom line: When it comes to reliability, tune selection and maintenance practices have a greater impact than the truck being deleted.

We have customers with high-mile examples that still run strong. Tune choice and oil changes make the biggest difference. The delete itself does not hurt longevity when done right. Increased power just means you watch things more closely.

What Are the Pros and Cons of Deleting a 6.7 Powerstroke for Horsepower?

Trying to weigh the good and bad of a delete? We help owners decide every day and list the real trade-offs. Power gains come with responsibilities.

Pros include better throttle response, cooler EGTs by 200 to 300 degrees F, and 1.5 to 2.5 MPG gains. Cons include lost factory warranty, legal risks, and more stress on the turbo and fuel system.

Pros

• Better throttle response. The truck reacts faster to pedal input
• Reduces exhaust gas temperatures by 200°–300°F, because of freer exhaust
• Fuel economy increases (often rises 1.5 to 2.5 MPG in mixed driving)
• Smoother tow and acceleration
• Cleaner airflow to the turbo

We see these benefits on every tuned truck we test.

Cons

• Voids the manufacturer/factory warranty
• Is illegal to operate on public roads in many areas
• Increases strain on the turbo and fuel system
• Has higher maintenance requirements
• Causes resale issues or may have issues passing inspection

Higher power adds stress to the turbo and fuel system over time. We remind owners to plan for extra maintenance.

Adding a 6.7 Powerstroke delete kit does not provide a ton of power. The real benefit comes from an appropriate 6.7 powerstroke delete and tune kit.

The balance depends on your use. Daily drivers gain efficiency. Towers gain pull. We help customers match the setup to their needs so the pros outweigh the cons.
