58mm Throttle Body Do I need special tuning when swapping from a 52mm to 58mm throttle body? Will it even idle or even start? I need some technical recommendation from anyone that have done this swap. Thank you.

you MIGHT run into some minor TPS problems causing erratic idle. has something to do with the way the TPS mounts giving a reading as if the throttle blades are open when they are not so some people notch the sensor holes to adjust accordingly. my summit brand 58 worked great without tuning but i know 3 other cars that used the same one (one of the cars has my exact same setup) and it game them all some varying levels of grief.
