i just had an idea for you!

do you have boost by gear and rpm?

if you run boost upto your traction limit in all gears then at 4th gear(or the last gear you use) 6500rpm or whatever make boost 9psi then you should be able to foot to the floor the whole way and limit 140mph and run a bit quicker time! or just hit the brakes at the end hehe

may as well use all your power for the start of the run where it makes all the differnence to your time, and just limit your mph. do you spin second or third on those slicks at full power? i can put down all my power in second on street tires on the strip and all my power in first on slicks. but mine is 125mphish car.
