S5 T2 wastegate?

Any educated guesses, or experience, as to how much boost creep there would be with a chris sanders TID and a 3" turboback on a series 5 wastegate?

Probalby not much but it depends on a few of your other mods...boost controller, boost level affect that as well as the exhaust and intake.

I get crazy creep.
I am connecting the wastegate directly to the compressor, so it should open up at 5.5psi and stay there rite? Nope

1st = 8psi
2nd = 10psi
3rd = 12psi
4th = 13psi
5th = 13psi

2.5inch turbo back to dual 2.5inch Y-pipe
3 inch TID
I have a 90 jspec in George's car

I can't even floor my car in 5th...

I keep enough pressure just to have the boost stay at 13psi

damn, I had boost bleed with my S5 turbo on my 87 with full 2.5" single exhaust and the Banzai TID. I would hit about 1 bar then it would fall to .6 at the top of 3rd and 4th.
