I removed the muffler on my Vmax to get that nice loud sound without having to spend any money, and it does but when it kicks in to V4, it drones bad and rattles the whole truck. This was an easy fix and is much easier than an INtune.

I had my doubts at first because I own a programmer for another vehicle with many options to choose from. But best bang for the money especially sine my jeep would not get out of its own way. The performance module had an impact from low to mid range. I could chirp the wheel and I went from stock wheels 16 inch to 20 inch. don't know about gas milage since i can't keep my foot out of it for the power. I would recommend this product to anyone especially with the 3.7 litre 201 horse power.

GM knows this is a problem yet they have not recalled these engines. I feel I purchased the Range device In time before any major damage was done, I installed it and ran high octane fuel and some injector cleaner and my truck has never ran better. I don't notice a difference in fuel expense. I hope it works for you.
