Im posting this thread to confirm that Porting the wastegate hole on the turbo (if you are running an external wastegate downpipe) will get rid of the boost creep, and boost spiking issues. you must port the hole to 11/8. I removed the exhaust housing side of the turbo to do this. remove downpipe, then carefully take the turbo apart, also i recommend changing the stock turbo oil feed line to a stainless braided line do to engine movement and vibration, good luck i noticed a huge differce in my car.
