Eww, 87 octane. You really should run 93 in your car.I like the setup of my car. The 5.0 wouldn't be bad though. I only get 276 rejoicing on 87 octave lol. Its more than what my old car had so its plenty.
Actually I think the difference between his car and my car for example is much like the difference between a 4th gen Z28 and an SS performance wise. His car stock should have about 15hp over mine stock.^your car is basically identical with a 4.6 instead of the 5.0 isn't it?
