So it's been a long time since I swapped turbos...back 15 years ago, I needed to port out the WG hole to near the same size as the Terry Houston downpipe oversized puck to control boost on the GT6131e turbo with .63 housing..back then the inside edge was not smoothed either which I smoothed out and ported out the hole to near the TH puck size.
Just got a new PT6466 with .63 exh housing, the inside edge of the WG hole is smoothed, but the hole is tiny.
I use the stock WG solenoid and a BstCommand controller and HD 18# accuator.
Do I still need to port this guy out or would that not be needed since the exhaust wheel is so much bigger?
