2006 Envoy Denali

Reviewed By John C (Reynoldsburg, OH) Reviewed for a 2006 GMC Envoy —8/1/2015 6:57 AM

Purchased this for my 2006 Envoy Denali. This unit works as should disables the motor from going in & out of V8 mode did loose about a mile a gallon, but totally worth it.

Reviewed By jeff l (POTTSTOWN, PA) Reviewed for a 2003 GMC Envoy —8/22/2013 10:56 AM

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.

The quality of this tuner is great BUT UNLESS YOU ARE WILLING TO SEARCH OUT HOW TO PROPERLY INSTALL THE CUSTOM TUNE YOUR OUT OF LUCK .... THE INFORMATIONS SUCK BIG TIME expect to search out on the web, YouTube and other places that will help with the download and tuning unless you don't mind using the preloaded tunes
