Very noticeable increase in power

Very easy to load and unload tune on your car. I noticed a big increase in turbo boost off the line and much smoother acceleration. I would highly recommend this for the HHR SS.

I did some homework and decided this was the reprogrammer for me. AutoAnything had the best price so I took the plunge. Installed the program and am totally happy with the results. My "butt dyno" feels the difference. It won't peel the rubber off the tires but the performance change is there. MPG has gotten somewhat better too. All in all I'm a happy camper and would recommend this product.
Biggest Bang for your Buck$!

Direct Injection, Turbo, Intercooler, Check. Cold Air Intake, uh huh. Launch Control. Roger. Automatic Tranny. Boo. Detuned to 235 bhp, there was more Chevy could've done, but Superchips DID IT! WAY MORE power, bonus mpg gain offsets heavy right foot. HHR SS guys, for less vacuum and more boost GET ONE!
