boost leak? Split intercooler joiner?

[Aidan D.]

Ive had the fmic off and checked for leaks. ive gone over all the vacum lines. ive changed fuel pump, afm,and pretty much every other sensor and solinoid.

ya my bet would be on intercooler leak

I changed actuator but it didnt make ne differance

the rubber pipe that goes onto the turbo inlet its a straight pipe! Could be perished on the underside! Worth a double check

Try the gearbox speed sensor a guy I know had a similar problem. Something to do with the ecu getting conflicting inputs from the gearbox and cutting the power.
