Hmm never had that problem with my GT500 i still the cast iron block before the switched in 2011.I would be almost tempted to race you in my L99 lol.I heard you didnt get full boost untill the car is broken in and the ecu wakes up alittle.Still a badass car you got any drag times for it yet.

Also thanks for the compliment.

I actually tend to agree. It's a heavy car though, and it was pretty warm out. These things pull mad timing when the air is hot and it takes quite a bit of power out of it.

No. Some guys are getting them into the low 12's but I'm in Las Vegas @ 2000+ ft elevation and warm air... That said, I'm going in October so it'll be cool and we'll see what it turns w/ stock tires, etc. It's an awesome car though.

yeah i live in texas im at 500ft lol great for drag racing.You could prolly run high 11s here.

Isn't it hard to race your computer game GT500 against a real car? just saying...

My 2013 E class smokes this thing.. 550hp are you sure?? That is a pretty slow time! I get to 110mph almost 3 seconds faster with 30 less hp and the same weight.

Car looks slow for 580hp.My 2010 GT500 was faster with less hp.Is the car not broke in most new camaros dont start running good untill the 5000 mile mark.
