Raced a couple of my friends last night, rx8 has full exhaust, intake, not really sure what else, but pretty much all the bolt ons there is.
Formula mods are in vid notes.
I have a misfire that i cant figure out on my car, and every time it happends its like an instant 6 or 7* of knock, its a very intermittent misfire but when it sees all that knock it pulls timing like crazy. When the TA starts to walk away is when my car misfired.

other kills not on vid. Stock 350z, walked him from a 40ish roll. Modded cobalt with down pipe, injectors, bigger HE and a 3.0 pulley with many more supporting mods. Put about 2-3 cars on him from 40-120.
