ok, let me clear that up my tuner isn't the exhaust or actuator guy. I bought the car with a 14psi tune in it done by a sydney tuner. When I called that tuner he told me it had been tuned to a manual boost controller hmmm. This is well known tuner. Anyway, actuator is dying as well but it has 1000cc injectors, cooler, pump and some other stuff I did so see what happens.
