Performed as promised

Reviewed By Christopher W (Troy, MO) Reviewed for a 2007 Hummer H2 —3/5/2015 11:00 PM

Installation wasnt as easy as stated, had to trim my "factory off road cover". But once that was done, this unit woke up my 6.0 LQ4. Had it for a while now, only bumped mpg by 1 gallon,,,, but worth it! Especially when I show other H2 drivers my readings!

Hummer H2 2003 with Jet Stage 1 performance chip

Reviewed By Olli T (Powhatan, VA) Reviewed for a 2003 Hummer H2 —5/13/2011 4:57 AM

Easy installation, took less than 1/2 hour, putting back the plastic computer cover was some work, cover is little small with the new chip on. With KN cold air filter, Jet mass flow sensor, JBA titanium ceramic coated shorty headers, AfE exhaust 2 x 3" pipes with flow through muffler, my Hummer sounds and feels like a real muscle car. But, now with Jet Stage 1 chip, there is instant additional kick: very notiable improved throttle response and feel of extra power when accelerating. The vehicle just feels like running with much less effort.
