Use as little octane as you need to cure detonation. There is no need for >100 octane in a bolt-on street car like yours, it will slow you down. Take tools to adjust your AFPR, pump up the front tires to at least 40lbs, do not lower the rears UNLESS traction is an issue, but I assume it will not be, run the car as cold as possible (I like to run with the needle BELOW N), ice the intake, move the pass seat all the way back (unless you yank it out completely), remove excess weight like the spare/jack. Open your hood as soon as you are back in the pits, turn your heat on as soon as you are done with your pass and are on the return road, make sure the radio, heater, and such are off before you run, AND HAVE FUN!!! With that MAC CAI you may also want to try removing your passenger side turnsignal and use a dremel to open up the little hole there to let cooler air hit the filter as it is positioned right behind that side marker light. Hope that helps...
P.S.- I wouldn't go below 25lbs of air in a normal street tire if you do end up letting air out of them. Also, try a run powerbraking it (as soon as the yelows start coming down start applying the throttle with your foot still on the gas... this will bring the revs up a little and help you get to the 60' mark quicker, then also try "stabbing" the throttle on the last yellow (always start to go on the last yellow) as this will "flash" your converter and will do the same thing as powerbraking it (some cars respond better to one better than the other). The first 60' is where its at if you want to be quick.
