MAP Sensor Upgrade
 

Does anyone know if you can have the gm MAP sensor upgrade for a 2008 hrr ss. I can find them for 2009 and 2010. But haven't seen one yet for a 2008.

Are you asking about these CED LNF Stage Kit CEDLNF1

I believe this is what your looking at!

19212670, GM STAGE KIT,

The Bosch Tmap sensors in the Stage 1 or GMTU kit are the same for the 08-10 SS's.

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.

Yes this is what I'm talking about!

The kit is a dealer installed and the computer is reflashed

Okay so once the kit is installed the computer has to be reflashed? Just trying to make sure before I buy it.

Firemangeorge has the kit, he can confirm for sure!

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.
