i have a 98 GMC Sonoma with a 4.6 (V6)and you can hear it grab second gear! but if you dont like the way it set up itself you can go back and customize each and every set up (tire size, gear ratio, rev, speedo, shift fermness and alot more!!) if i was a Kindergarden teacher i would give it a GOLD star!!!

Suprising Electronic

Reviewed By Justin W (Livonia, MI) Reviewed for a 2001 GMC Sonoma —12/16/2009 2:44 AM

I was very scared at first, the module is made of plastic and trying to secure it into the ECM was nerve crunching at the thought of snapping the plastic. After a hard start, the module adjusted the factory settings and damn, I was off. At an average I dropped off a second and a half on my 0-60, haven't tried the 1/4 Mile yet. I'm interested to see. Any Fuel Injected vehicles NEED this chip!

2011 AVALANCHE tune

Reviewed By George S (SAINT PAUL, MN) Reviewed for a 2011 Chevy Avalanche —5/2/2016 11:26 PM

Easy to install but be sure to follow instruction. (Pull proper fuses). Disconnect (8-4 cylinder) drop out. You will have a smother , quieter and more responsive engine. There are also two options to try the premium option and the regular option I have yet to try their premium option but I am very satisfied with the regular option. For my money it was well worth it.
