HHQAFM/DFM Disabler Active Fuel Management Disable Device Compatible with V6 & V8 Gm Motors New Technology RA003

Works great put in truck and what a difference. Keeping it in V8 mode is actually saving moneyI am getting better fuel mileage. Saves $20 every week at the pump. So it's already paid for itself,I recommend it to everyone.

Initial post…Heard a bunch of people buying a disabler but couldn’t see myself spending $200+ for the Range AFM disabler, I ended up purchasing this one. Does the same thing, but if you want to buy the name brand then be my guest. This works just fine. No issues. Just plug it in and enjoy that V8 instead of V4.UPDATE February 5, 2024…After testing it out for a couple of days, I began noticing my V8 going to V4. I thought it was maybe a glitch or something but it continued to do that. So, I requested a refund and I ended up getting the Range which I did not want to spend money on. I guess sometimes you get what you pay for. Great customer service though and return was free through UPS label and refund was received same day.

When first installed on truck I saw it flip between V4 and V8 one time really quick while driving and hasn't done it since. Been using it for two days and I've noticed my truck drives better and is getting better mileage as a result! Overall good value vs paying double for the ranger version of the product. Cheap housing that feels flimsy but the product works. No instruction manual explaining the indicator lights. Red on constantly when plugged in. Blue Flickers sometimes while driving...assuming that means its working and stopping the V4 change during those times it flickers but again just assumptions.

Arrived quickly. Simply plugged in and no more V4/V8 switching on my C7 Vette. All V8, all the time. Little if any impact to mileage! Shape makes it easy to remove & insert (you should remove when not using car for extended periods to avoid battery drain, or leave car on trickle charger). No error codes or any other problems so far. Happy, price not exorbitant like some other brands.

After biting the bullet and purchasing the AFM/DFM - I was extremely skeptical, upon arrival installation was easy and with excitement I tried it out - and there is a definite difference in performance - then there was an ''Issue" after reaching out - honestly I was not expecting the quick response from the Company - but they Resolved the Issue with professionalism beyond my belief. I would definitely do business with them again.
