How much does changing the stock throttle body to a 75mm affect a/f ratio on a supercharged application? Will it require a retune? I am at 11.8 so I dont have alot of room to play with.

As long as no changes to the MAF everything should work fine. Of course this assumes that the MAF is not maxed. Remember, the PCM computes the injector duration based on the MAF signal. As long as the PCM has an accurate read on the mass of air entering the motor, the injector pulse width should be correct.
