I also own a 2007 GXP and just picked up my IBM 5-speed SS last friday. Love the SS. My GXP is Hahn Racecraft's test mule and it was the first GXP that they put the BSR tune in. The BSR tune makes a really big difference in the way the car performs and the Bosch computer doesn't override the tune. The nice thing about the BSR tune is it can be installed and uninstalled in just seconds with the hand held PPC tuner. My GXP is an automatic and the tune was a major improvement. It really pulls hard going through the gears. People that I've taken a ride can't beleive its a four cyl. Here is a link to the GXP tuner. http://www.turbosystem.com/New_Folde...ll%20Sheet.pdf
I've talked to Bill Hahn about the BSR tuner to see if it would work in the SS and he wants me to bring up my SS so he can scan the factory tune and get with BSR to see if it will work or if they are going to make a tune for it. I need to go pick up my GXP (as soon as it is ready) from them as they are doing a turbo upgrade, bigger intercooler and some other neat stuff to it. It should be a real beast when they are done with it.

[QUOTE=Darkcyde HHR SS;249569]Yeah usually around 5-10 HP with a Catback depending on how free flowin the stock one already is.QUOTE]
Probably not even that with the stock bottleneck at the o2 housing, downpipe and cat. Need to go TBE (turboback exhaust). Then the turbo will be spooling nicely.
