Power all the time
Works great and the price you can't beat my 2017 Silverado v8 mode all the time.

Works as it should
Plugged it in and immediately started working. All 8 cylinders when I need them. Will buy again if needed.

Inexpensive temporary solution
Verified no codes present. Plugged into OBD2 port. Put DIC in instant fuel economy showing MPG V8Drove 60 miles with cruise on 55-65 mph and truck stayed in V8 . Previously I would have to place shifter into manual 5 mode to do this. Notes on AFM constantly going from V8 to V4. There are about 9 things that can cause this. For the price of this disabler, I can take my time slowly going through the list. Until then, when I know I’ll be on the freeway, I’ll just plug this in. So far so good- and I assume no damage is being done to the ECU.Generally speaking the AFM doesn’t like any misfires, cam positioning disorientations, MAF discrepancies, Vacuum leaks, and other trim involved fuel mixture O2 sensors /modules being out of spec- for lack of a better word.I’m still learning, and I’ll update if anything changes.

Lo recomiendo al 💯%
Al principio no supe como instalarlo ya que el port no era el indicado, posteriormente lo instale al correcto y funcionó inmediatamente, lo recomiendo al 100% funciona súper bien

Works like a charm. You notice the difference immediately
Haven't had it but for a few days on my 2014 Sierra 1500 and that's the only reason I'm giving it 4 stars instead of 5. No more weird stutter/bucking going from four cylinders to six to 8. Made driving a much smoother and enjoyable experience. Just feels much better to have all the power your engine is supposed to have all the time. So far haven't noticed but a very slight difference in fuel consumption (14mpg-13.7mpg avg). Would recommend and you can't beat the price compared to other brands.

Buyer Beware
Was installed less than 30 minutes. It shut the engine off, and would not restart until removed. Changed the computer programming. Has been removed for over 45 days and transmission still does not shift properly. Constantly hunting for the correct gear and going into neutral between shifts. Goes in neutral at stops, have to Rev engine to go, and than engages hard.
