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.

My H2 response is dramatically improved. Much smoother acceleration, better shifting and overall driveability. Very pleased with purchase.
