Reviewed By Kurt L (Novi, MI) Reviewed for a 2008 Chevy HHR —8/24/2011 5:59 AM

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

2006 HHR 2.4 automatic (Hopeful Hot Rod)

Reviewed By Sam s E (Brighton, CO) Reviewed for a 2006 Chevy HHR —1/9/2011 9:23 AM

The module plugs into position 2 on the ECM. Position 3 is the exact same connector. Be careful. My car had an IMCO 2.5 inch muffler and a K & N intake. It really made a difference in power and noise. The car is much more responsive and fun to drive. The exhaust was louder but all the hills got smaller. It just feels good. Mileage did not change yet. (27 +/-) It has not been above 30 degrees for 2 weeks. I am sure mileage will get better when it gets warmer. It was well worth the investment. Sam, Brighton, Colorado
