2006 - 2011 2.4L HHR Performance Tunes

The 2.4L Chevy HHR can be a fun little wagon. Even though it lacks the raw power of it’s SS brother, the 2.4L is still no slouch on the street. Our Stage 1 performance tune adds a great deal of low end torque to get the HHR moving off the line, and gains across the entire powerband to keep you moving. If you own one equipped with the 4-speed automatic transmission you will also benefit from our TCM retune, included standard in all of our HHR Stage 1 Performance Tunes.
