Question FAST 78mm TB?

i have a 98 Z28 and cannot decide whether or not to PP my stock TB or invest in the FAST 78mm TB. i know the PP would be a lot cheaper but the FAST would look nicer and allow me to upgrade the intake later. Would the FAST 78mm be a direct bolt on with NO modifications? Would if have to set or calibrated? Thanks for any info you have on this TB

My car only has 51,000 miles on it and has been babied. I have been showing it some and think the 78mm would be the best way to go. I just don't want to get it on and the car not run as well as it did with the stock TB. Nobody on here has really posted anything about the 78mm on a stock intake so I want to gather all of the info that I can. Thanks

i have never tried it on a stock intake (don't know if it will even work), but i can tell you from experience that if your using a ported t/b and switch to a fast or wilson 78, you will feel a difference.
