I'm on an AMS 35R with 38mm gate and HTA mod.

I do get some creep at lower boost levels (around 26 psi). Like I'll hit 1.8 bar and it will creep to 2 bar. It doesn't really bother me too much although if there was an easy solution I might be interested.

heres the picture of the manifold as it sits right now im ripping the motor apart to drop in some pistons and rods so i can take full advantage of the 35r

I haven't noticed any creep from my ETS PT61BB. I did upgrade for the Tial 44mm though and I'm running their short mani. Run 25-26 psi on pump and she stays right there. Hallman MBC

I think we are going to put a 44mm wastegate flange on it to stop any type of boost creep. It's possible to use a 38mm wasetgate with the 35R and have no creep, but it requires some tinkering and tuning with the boost solenoid to get it to work out right. Sometimes it's easier to just add a 44mm wastegate then tinker with the little things.
