no boost on my gt4 st205 Options

[pikey]

hi can anyone help me please! went to drive my car back from my army camp and it had been working fine in the morning. obviously i let it warm up before i give it any kind of boost, at least 1/4 up the temp guage. the car was warm and i put my foot down. there was hardly any power with the boost going to 0 wich is vaccum pressuer i believe. theres a strange whining noise aswell.

ive had the turbo off and its all fine, there was however a little oil in the induction pipe but not much. ive checked all the vaccum and boost hoses and they seem fine. in a nutshell im running a motec m4 pro ecu with 1.1bar boost, 3inch exhaust from the turbo with 2.5inch restrictor so its not overboosting and a few other bits but theyv all been on for at least 6 months with no problems.

so all i can think of is maybe the actuator or a sensor or something. can anyone shed any light or give me any contacts please thanks
