This not only disabled the irritating 4cylinder mode but as a pleasant side effect this also cleaned up the erratic transmission shift points. My truck now runs as a 5.3 liter V8 should.
I’m honestly surprised. Best $50 I’ve ever spent.
Do it 👍

AFM/DFM Disabler RA003 | Disable Active/Dynamic Fuel Management

Appears to be working flawlessly. Excellent price and so far haven't seen a significant change in milage, plus throttle seems more responsive. Hopefully this helps my Jasper replacement engine live a good long life.🤞

Does exactly what its advertised to do, completely shuts off the V4 fuel management system. Also, I noticed no pedal lag. Definitely a lifesaver for the 5.3.

Happy with the AFM disabler so far. Would have like more updates before the unit was shipped.

very happy

Bought a egr block for my 1993 gmc suburban 2500 454 it fit perfectly they sent new hardware to mount but I just used old nuts cause it was easiest. Fast and perfect couldn’t have been better

EGR Delete Kit for 2020-2022 LM2 3.0 Duramax Chevy Silverado GMC Sirra 1500

Exactly as described. Perfect fit.

This amazing piece helped me solve my issue with hesitation when accelerating.
Previous owners installed aftermarket headers without the egr line hookup, that being said they snipped the egr line coming from the valve location.
Thus causing the egr valve itself to act erratic under acceleration. Couldn't appreciate the people who create these parts enough, no more egr!!

Great product fit perfect and it looks great.

6.0L Powerstroke EGR Delete Kit for 2003-2007 Ford F250/F350/F450/F550

Works as advertised. Truck feels like a different vehicle. Transmission is even liking the smoother power and is shifting much better now.

So far so good with my AFM delete on my 2017 Silverado
5.3 with the factory sport exhaust. I haven’t driven far yet but I can already feel the difference at low speeds being my V8 mode is always on now. The light goes off after shutting my truck off so no battery drain. Before my truck had like a flutter sound at low rpm at speeds around 40mph I guess that’s when my V4 mode was kicking in. But instantly that’s gone now also just slightly pressing the gas pedal now the engine comes alive quicker than before. I’m very satisfied so far and for the 40s $ price range. I first looked at one for around 300 bucks. 5 stars I’m impressed thanks
