I read a 75mm T/B will lean out your car up to 30% And because my car isa N/A wouldnt a 70mm T/B lean out the car less and still give you the same Throttle response? What about MPG?

Why would a bigger throttle body lean you out? Is there air sneaking in past the MAF sensor?

Because the motor is able to take in more air than it could with a stock th/plenum. If the computer is not tuned to compensate, the car injects the same amount of fuel as it does stock, but with increased airflow, which in turn causes the a/f ration to lean out.
