I have a k&n air box a jet mass flow air sensor and magnaflow exhaust on a 2.4 hhr I just put the stage 2 chip . these guys should have written the original code from GM my car runs way smoother with chip exhaust is not over loud because GM code has it in wrong gear or wrong air or fuel flow. I have great response lots of power and a mutch more even way to distribute that power . And my gas milage has jumped up I do not have numbers but I would say at least 2-3 miles more per gallon. That is if you can keep foot off of pedal
