The stock throttle body is 60mm and the stock mass air is 58mm. The stock throttle body goes along way. I've gone 11.50s with a stock throttle body.

i was looking for TB on ebay and other sites and i seem to be just finding 75mm, how much does it usually run to get one re-calibrated if that is even possible

Throttle body or mass air meter? I'm not sure what it costs to calibrate a mass air meter anymore but it is done all the time. C&L uses interchangeable sample tubes but there are sometimes driveability issues with their meters.
