Those were from the previous run. The 510 was at 100RPM. We're looking at 342.9HP @ 5500RPM and 354.3TQ @ 4700RPM. Pretty sick for just a tune and a makeshift intake!

those r pretty good numbers for a new car!
So wat kinda tune u have on it, other than the intake!
cause i'm plannin on gettin one, and i wouldnt mind to make it work a bit harder :P just waitin for it to get to Canada!

I had my tune done at Vector Motorsports. The intake had to come off because it wasn't fabbed...just a mock setup. The current numbers are:
Stock RWHP: 304.8@5700
Tuned RWHP: 335.1@5600
Stock TQ: 315.3@4600
Tuned TQ: 348.0@4700
MPGs actually increased about 3MPG although I expect that number to drop closer to 1-2MPG.

So when Pontiac says it gets around 360 HP they mean at the fly wheel then, right??

Yeah...estimate about 20% drivetrain loss on the Automatic although if you run the stock numbers, it looks like its closer to 15.5%.
I'm pretty sure that unless it says RWHP, that most HP numbers are rated at the flywheel. I could be wrong though.
