Don't make a mistake, get a stage 2

Reviewed By Robert F (Venice, FL) Reviewed for a 2003 Chevy Trailblazer —10/8/2008 9:32 PM

Almost got a stage 1 but after reading reviews I realized I would not be happy with a stage 1 considering I had a K&N cold air induction and a cat back Flowmaster exhaust, I was right. The stage 2 is what I woul have expected from a stage 1 so get a stage 2 if you want not to be dissappointed.

Computer programmer praise

Reviewed By John L (Puyallup, WA) Reviewed for a 2007 Chevy Trailblazer —4/28/2014 11:06 PM

It was easy to use I set it up for premium fuel car runs better and I gained about 1 mile to the gallon with mixed driving. I tried to install a jet mass air sensor but it turned on all the dash lights so I had to put the stock one back on then I saw where you can't piggyback with this programmer but I'm totally satisfied with the programmer.
