ok just to clear things up blauparts.com used to offer performance cams and you could send in your throttle body and have it bored, but no longer offer this service due to a lack of intrest from the public it was part of a 12V performance package but could be purchased individually

^ Mance there does MAFs, throttle bodies and a few other things. His handle is VAP.

 

Do you know anybody who does the 30v's...?

 

no need on the 30v... if you look at the throttle body it's hardly a restriction. The 12v TB has 2 venturis that can be bored to increase flow.

 

I was told that there was restriction and it's best to get it bored out...
