The Chevy HHR platform is one of the more unique performance platforms in modern automotive history. The SS model gives the portly wagon an excellent suspension and a power plant that is capable of putting down wheel horsepower similar to a small V8. It takes little more than just a tune to gain significant amounts of horsepower and torque from your LNF powered HHR SS. RPM Motorsports writes Custom Performance Tunes, and manufactures Intercoolers, Chargepipes, Downpipes, Fuel System Upgrades and more to get the most performance out of your 2.0L LNF Powered HHR SS and 2.4L LE5 Powered HHR Wagons.
