Even if you do not have a RS232 out, its not to hard to figure out the resolution and scaling of the voltage going to the gauge, build a table, and use parallel or RS232 input on a laptop to log and display.

530hp to over 2 tons of weight???
There are plenty of cars with higher power to weight ratios that can hook up. If one placed better gearing in the car, as it probably has a high numerical final drive for all of it's 130 some odd horse, he could drive the car in a non retard fashion.
