So as it says.....How fast have you had your SHO up to? What differential do you have in it, 2.77 or 3.16 final drive? Looking to hear more from the tuned guys. How much boost?
I've had mine to 140mph at about 18 psi and it was slightly up hill when data logging...I was close to the top of 5th gear I have 3.16 FD...It was still pulling pretty good.
