Quick question reguarding S5 turbo.
I'm new to the whole turbo motor thing, always had n/a's before! I just installed a new S4 motor into my 87 TII, I swapped the turbo out for a S5 with a ported wastegate and as far as I'm aware they run higher boost stock than S4 turbos correct? Now, will I hit boost cut with just this turbo installation? I'm worried that is a possibility. Any help would be greatly appreciated, until I get a FCD I'd like to drive it without worry.
Thanks alot guys.

Top Down, Boost Up

But running an S5 turbo without the S5 turbo duty solenoid (can't use it anyway on an S4), will let you hit ~6 psi. The wastegate has the same 5.5psi spring as on the S4 turbo.
Besides a boost controller, only boost creep will take you over this pressure level. But your wastegate is ported, so that shouldn't be a problem.
