Valve springs? When runing FI those of you that switched from stock springs to the comp.918s or somthing similar. Could you tell a differance in performance? Also did it change part throttle performance any? Thanks.

DEFINITELY. My car was falling on it's face starting @ 5200rpm. And it did seem that part-throttle picked up also. Re-dynoing tonite since the springs, I will be in the exact same configuration other than those. So comparisons should be easy, I'll let ya know!
