I also have a feeling that GM's secret horsepower "estimate" is actually closer to 600. That seems to be the most likely case in my opinion especially when you look at the raw HP to weight ratios of competitors.

When I buy mine I will likely just get the windows tinted and a tune. Can anyone tell me if a tune voids the warranty?

And PLEASE if anyone is listening or has the power...tell GM to offer a good Orange exterior color option (like Dodge or a newer version of Hugger), an automatic transmission, and other wheel options. I dread the day that I have to pick between my three 2nd choice colors. Sorry for the long entry. I will go back to just reading now .
