Jeff-
Ive read that the 43 should be in the 5.9 sec 0-60 range. I am guessing that may be a little conservative, but not 100% sure. I have seen the 0-60 times ranging from 5.9 to 6.5 secs, but that really depends on many factors.
What engine mods are currently on your car?
Do you have the original G-Tech, or the new one? How accurate do you think it really is?
Do you think stiffening up the rear suspension would help keep the wheels on the ground?
