Not too bad for a 3800 lb. 4 door family car!
102mph traps...no wonder it was so ugly from a roll on. IAT issues?? TM usually kills near the shifts... this thing didn't seem to have much going on anywhere.

Not the fastest but still good for a 4000+ car not 3800. People have been 13.3's stock @104. I'll take mine to the track in the next few feeks. Everyone says the GXP is not worth the extra money. Good Kill

We just got a new G8 GT a couple of weeks ago for my wife. It is decently quick, but the trans programming SUCKS! It has the updated calibration, but that didn't help much. Still has a huge delay between shifts. Guess we'll have to just get a tune for it and set it how we want...pick up a few hp too. Need to put a few easy miles on it first.

I really wish they would've sold these with a manual trans for the US market. Would be much more fun IMO. Great car otherwise.

I thought you could get them with a six speed? Or is that just the GXP? Either way, get the wife's car dyno tuned, maybe some bolt ons too. They are supposed to run lower 13s with intake/tune.

Nice run S8ER. I also figured the G8 would put up more of a fight. I've been looking to run one, in the Z28, but the only one in the area has way too much work for me to even want to mess with. Now, with 2nd gear gone, and the Camaro going to a new home sometime soon (hopefully), looks like I'll never find out how the old LT1 would stack up.
