62MM Throttle Body

Apparently, the stock Throttle Body on a 91-95 4.0 is 60mm. However, the opening on the intake is 62mm.

Has anyone had their throttle body bored out to 62mm?
Do you notice any increased power and/or change in fuel economy?

Search around it may be 60mm at the openings but it tapers to 58 or 56mm at the plate. I recently purchased a TB from Fastman Throttlebodies that is 62mm straight through.

It smoothed out accel. and shifting made a pretty noticeable difference at all positions of the throttle. Recommended. YES.

Very nice gentleman, price is right, and it is a one man run shop. Bullshitted w/me for an hour about hunting.

Any change in gas mileage?
