    Was a little skeptical at first , but after reading alot of similar reviews I decided to give it a try. Works as stated and couldn't be any easier to use. Happy with outcome so far.

    Product was easy to install and helped my truck 100% with the shifting to 4cylinder mode in between shifts.

    Great Product A MUST have

    I would recommend this Range device to everyone who has GM AFM engines. My truck shifts less, fuel economy is the same, no more dry cylinders, cam lobes or lifters. I wish I had bought this 3 years ago. At 80k miles I know the lifters are going to turn in their cheap plastic guides if AFM is active.

    I wish I bought it sooner

    I had been eyeing this thing since j bought my truck 2 years ago and finally pulled the trigger. It completely fixed my trucks issue with the torque converter hard shifting or stuttering during hilly conditions where v4 mode would activate. The truck drives and shifts much smoother now during those situations. For daily city driving i notice no hit on the mpg either. However for highway there is a slight hit, maybe about .5 to 1 mpg.

    Different truck

    It works, keeps all cylinders firing at all times eliminating the 4 cylinder vibration and constant switching from V4-v8 at higher speeds.
