No major problems with it

Reviewed By William K (Chicago, IL) Reviewed for a 2003 Chevy Astro —11/23/2011 6:11 AM

Instruction manual was incomplete; did not have my Astro van listed. Called help number and they helped me. Can't really feel any difference in performance. Haven't checked gas mileage yet.

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.
