I'm having some trouble getting my t6 S480 to spool up so this is what I came up with. It used a wrx wastegate I had laying around which will have its own boost controller so I can adjust when the flapper opens. The divided housing was originally a 1.32 ar. So I figure its now .66 before the flapper opens now.

Well I tried out the quick spool on the street and the dyno. It didn't work to well for me. It ended up only hitting about 4psi with the quick spool closed and the flapper never opened (should have around 12~14psi). I disconnected the flapper to let stay open and the boost went back to 8psi. This was all done with the wastegate disconnect. I even went a step further and covered the outlet of the wastegate with aluminum foil to confirm the wastegate wasn't venting. At this point I have decided to dig into the car again. I plan on redoing all the pre-turbo stuff. Starting with cast manifolds and running smaller 2.5 inch piping to the turbo. Also thinking about selling this turbo to go with a t4 78~80mm turbo.
Thanks John. Your car is moving too. I wish I could get out of the hole like that. What is wrong with your fire suit? Single layer?

240zRacer- My goal is mid 9's.
An Update:
It looks like the wastegate was a limiting factor. I blocked it off with a metal plate and I now hits 18psi. I took it to the dyno again and laid down 695hp and 595tq sae corrected. I also tried out the spool valve again. It works! The car will now hit 5 psi on the foot break. I plan on trying co2 in to the ams1000 boost controller to see if I can achieve the same results as blocking off the wastegate so I have some control. I am very excited to see what I will do once the track opens up again.
Ignore the spike in torque, the dyno was haveing issues with the tach signal. It didn't make 800+ torque. It was more like 595 when you scroll the curser over peak power. To give you an idea of the power band; the power and torque intersect at 5200 and redline is 6600.
here is a picture of the spool valve.
and a dyno comparison with (blue) and without (red) the spool valve
I finally got some time to work on the car again. I Fabricated and installed the parachute mount and bracket.
Mocking up the bars
Welded in some gussets
Under the car between the rear axle and rear sheet metal. The trans cooler bolts over it.
Now with it all mounted up.
I still need to mount the cable and release handle inside the car.
