In case you didn't know this, you can't just install the 3 bar sensors without adjusting the calibrations in the ECM, Car will run like major crap.

Honestly. The GMTU or Stage 1 kit was fine back when you could get it and the factory powertrain warranty was still applicable. Since it was considered a GM product, your warranty was still good under the 5 year/100k mile coverage.
Now that all the HHR SS's are beyond that 5 year period, a better choice would be an aftermarket tune.
I couldn't see spending $800 (kit and labor) for the GMTU when there are some better aftermarket choices.
Also. Trying to find a dealer who is current and updated on installing the kit may be an issue. Remember that the SS hasn't been made in 6 years, so the dealer techs may not be too familiar with it.
