Easy plug and play and functional

At first I was skeptical, but it does work, my truck is allways on v8 mode, stupid DOD is by far the dumbest thing gm has come up with on trucks, I bought a v8 for the power on demand not displacement on demand, no check engine light whatsoever, I’ve had it for a week now and no issues whatsoever. Should’ve bought a tuner but this is a good cheap alternative. If you want your v8 to kick in when you need the power and not wait for that lag of DOD to stop and v8 to kick in, buy this, it’s easy to install and remove, ama look into a performance tuning plug and play device tho, I believe my z71 should have more juice to put out.

Hi there! We're thrilled to hear that you're satisfied with the AFM/DFM Disabler and that it works well on your truck. Thanks for sharing your experience and recommending it as a budget-friendly alternative. Enjoy your enhanced power and performance!

Does what its suppose to do (Stay in V8)

For what it is it does its job. I have a 2014 GMC Sierra. The truck has the fuel management system to where it will switch from V4 to V8 when there is a load and visa versa. This device will temporarily keep the vehicle in V8 mode unless you unplug it. Note: The only Con would be that obviously your gas mileage is going to be effected. Before I was getting roughly 18 mpg with the disabler closer to 15/16 mpg. (In the city). Would recommend this product if you want your rig to consistently stay in V8 for that extra power when you need it.

Hi there, thank you for sharing your experience with the AFM/DFM Disabler! We're glad to hear it keeps your Sierra in V8 mode and provides the extra power you need. We appreciate your recommendation and detailed feedback on fuel economy. Enjoy your upgraded driving experience!
