R32 Actuator --> Rb25

[KiwiRS4T]

sorry to hi jack, recently installed a rb20 actuator and now its overboosting to about 16+psi !. I've been reading and believe i hooked up everything correctly. I'm puzzled now :S. Current mods, 3'' bellmouth and zorst, turbotech boost T set to ~12psi and a nistune remap.

Prior to this problem I had another 1, my boost would drop from 12psi to about 10psi only in high revs (5500-redline), the actuator was suspected so i replaced with rb20 1 and now this

Any ideas guys?, only thing i changed during isntalltion was extending the vac line from actuator to boost T to cooler pipe to reach. :S

I take it you have ditched the stock solenoid? Tried adjusting the boost T (without regard to any markings on it i.e. adjust the boost downwards)?

I havn't adjusted the boost T yet. I just put the rb25 actuator back on and its back to square 1.

My next question is, does this mean the rb20 actuator is faulty? OR could it mean that i need to re adjust my boost T?

I only didn't want to touch the boost T was cos its tuned for the ecu already and i dint wana change the settings being a manual BC its very annoying to adjust to the boost you want. hmmmm

problem solved, was in fact BC. thanks for suggestions. Now its fun time fine tuning that tap .........
