Default Throttle Body Reconditioning?

Does anyone know of a business that reconditions TPI Throttle Bodies? Of if there is any way to do it yourself? THe shaft on mine seems to have alot of play in it. THanks

He drills out the bores to 52mm and installs needle roller bearings for the throttle shaft. New larger throttle shaft blades are then installed. A minor modification is then performed to the egr passage to make it perform correctly with the larger bores. Price is just over the $200 mark.

Arizona Speed & Marine (AS&M) is another source that can be tried. They will bore out your stock 48mm to 52mm and recondition as well http://www.azspeed-marine.com/

That being said, the Dave Koldos route is probably your best bet.
