Difference between manual and automatic
I see that the HHr list the 260 hp on the manual and 235 hp on the automatic! Can anyone tell me what changes they made so I might boost hp on a automatic? Maybe a chip or power module? Also has anyone heard what they are going to do for the 09 model in the way of engine hp? Thanks

I am willing to bet they aren't changing the power for the 2nd year of production. But yes, a PPC tuner would boost the power (when the auto is available) standard bolt ons such as exhaust and intake would help out a bit as well.

I've seen many different horsepower ratings for the A4 SS and from what GM Powertrain lists as the SAE J1349 test the A4 is 250 HP peak but limited to 222 lb/ft torque due to the maximum torque rating of the transmission. Horsepower is limited in 1st and 2nd gears by limiting maximum boost.
In case you haven't seen it, here is the SAE certified J1349 dyno graph:

Unless you are planning on Racing your SS I think the stock HP with an Auto is plenty. It has plenty of power that kicks in when you need it. I think once you get yours you will find that to be true. Wouldn't the dealer let take on for a spin? or didn't they have one? I took one on a 20 mile ride before I bought it and I was like this little thing has a WOW factor.
