Thanks. Once the new software gets here I'll make a run with the stock top speed limit.

I used to have an excel program that would tell you how much HP was required to obtain a certain top speed but I lost it in a computer crash. I wonder what the HP required to break 200 is on a C6? I believe that as far as gearing is concerned I can reach nearly 224 mph in 5th. That is with the rev limit raised to 6800. However I am not sure that I have the HP to break 200.
