"Porting, or increasing the size of, the wastegate will allow more exhaust to pass thru the gate. This will solve the creap problems."
Does anyone know what the stock diameter is and to what dimensions the gate should be ported to? Can this be done with the exhaust pieces removed and leaving the turbo attached to the car? My assumption is I should probably remove the turbo but it would save time if I didn't have to. Are there any gotchas to doing this myself using a Dremel or drill? Or should I have a machine shop do it using a heavy drill press?
