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.

I have ran multiple sizes of TB w/o a tune and it ran just fine. You should be ok man..you should be able to notice after the swap if anything is running strange. It's a fast swap if so

shouldn't have any issues

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.

Should be no problems unless like stevo9389 said about your tps take your time and get it done right question what 58 mm tb did you choose I know of some under 200 right now

If you don't need to tune for it why do you need it at all? I thought that the idea of a larger throttle body was increased air flow. Wouldn't more air require more fuel?
