Any pointers post-blown turbo to get the oil out of the exhaust?! This is embarrasing

who can custom tune an UrS4 on the east coast?
With all I'm hearing I'd rather have some custom work done. Maybe I should have Minhea cook me up one of his generic RS2 chips but with a bit lower boost, say 22 peak

Follow 4Driver4's instructions...
and just let the WGFV hang out. Also make certain it's facing the right way when it's all hooked up.
I wouldn't preload your WG anymore to gain boost, actually I would back that off. You should be able to make proper boost by computer control via the WGFV.
Check for boost leaks.
Once you have confirmed you are leak free I would run with the WGFV plug disconnected, no computer control. You should see 6lbs or so of boost, though you may see higher with a stiffer spring. If you see the same boost you have now your stiffer spring and WG preload is controlling your boost and not the WGFV/ECU.
Then if you are trusting of yourself and your boost gauge remove the lower boost feed to the WGFV, the hose from the compressor or boost source that feeds into the vertical port of the WGFV. Plug that hose with a bolt. Leave the WGFV connected to everything else. VERY GENTLY do some low rpm start 3rd or 4th gear pulls and watch your boost. Do NOT go more than 2-3lbs over what you have seen before with the WGFV setup hooked up (20lbs). If you can obtain more boost with the WGFV boost feed disconnected it will most likely indicate you have an issue with that system. If you don't see any increase in boost check you gauge feed and gauge. Then look at your wastegate or other issues. Running like this should allow for 30lbs+ of boost, be careful!
I went through all of these procedures with the search to find more boost in my 90q20vt and found it was a gauge issue, lots of work for a simple problem, then again it was good to double check all of my install work.
Be careful running the setup with the boost feed to the WGFV disconnected, you can run huge boost doing that and it can be damaging, so please be careful!
Cheers,

Nice picture...

Turbo Intake = Airboot
Compressor = Turbo
Wastegate = Wastegate
The longer horizontal barb goes in the airboot.
The shorter horizontal barb feeds to the wastegate.
The single vertical barb feeds from the turbo.
They must be oriented in this way.
