Combatting boost creep.. (GT2871R) - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Running 17lbs on 740cc's with a gt2871r 0.64 turbine housing, and I'm getting the usual expected boost creep at top end of higher gears..

Would a larger diameter external gate be my only option to combat the creep? It's creeping past the 20psi mark on my boost gauge. AFRS are 11.4:1

Oh and my actuator is fed off a hot pipe pressure source.

Any ideas would be appreciated.
