I purchased this for my 2003 Envoy XL 4.2L V6 for towing mostly. I also have a K+N cold air intake. My wife and I have noticed a difference in shifting gears, lower RPM's in regular driving and towing, more power where it needs to be, but have not seen a drastic change in fuel economy. Have only had it installed now for 3 weeks. I would certainly recommend this to anyone.

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.
