Waste Gates are Very Touchy , I Ported one ( Very Small Amount ) .025 ~ .030 with Larger Opening at Bottom where it comes from Exducer ( Exhaust Internal Wheel )
Near Center of Exhaust Manifold ~ Opened that Entering point , Like .062 ( Wow ) changed entire Waste Setting had to be Cranked Down to Build Boost . .
Took about .180 of sec. Longer to get Up to 23Psi , but Once there It Held Nice and Had much Better Top End 7200 Rpms where most Others were Falling Off at 6800rpm ..
I also did some Opening Up Boost Side - here's a - Before & After and a Polishing Inside Turbo - Before & After
