Throttle body

[M3RACER]

Anyone have experience with boring out there throttle body, is it worth it? Did it really make an improvement? Are you OBD 1 or 2?


Thanks

OBDII, Dinan did it for me, but I did it concurrently with a host of other mods, and judging from some #'s of comparable cars with similar mods, I'd guess it's helping.

Also, though, Osh at RMS recommended it for my 3.0, but recommended against it on Phillip's (aka ///M Roadster's) 2000 M 3.2.... So I think it depends on your car and the mods you are planning, etc...
