Very Pleased with results

Reviewed By THOMAS B (Rockaway Park, NY) Reviewed for a 2008 Hummer H3 —7/29/2014 5:06 AM

I had purchased other brands before for different cars and they were not that great so I was skeptical. I am very happy with the boost in performance this gave to my H3 5.3L V8. It has a much more responsive feel with firmer shifts which I like. So far I've only had time for the 87 Octance Performance Tune but I want to give it some testing time. Not only is performance better but it added 1/2 MPG to my average at the same time. Can't wait to try the other features.
