Has anyone had there throttle body bored or honed to a bigger size? I've seen a lot of import cars that have had this done. I wondered if it made that much of a diffrence.
Mines .060 bigger and repolished with a power hone. Not much difference if any and you'll have to make a custom throttle plate also. These TBI units flow enough air for 275+ H.P. but I wanted to see myself if it would. I wouldnt recommend doing so.
