Boost pipes won't be pressurised unless it's under load. Also I would be worried if u could move the actuator by hand. Mole grips mean it's working. I would say it has to be a boost hose off.
So after removing and checking pipes the turbo no longer whines. Still no boost. Mates run odb/obd thingy n it's misfiring on cylinder 1. Said it might be running in limp mode so gonna sort the misfire out first.
I have a turbo for ktec as they do not modify the hot side for their hybrids. Rs tuning need a turbo with the hot side on.
If going for a hybrid would need decat, arp rod bolts and uprated injectors. Had to do this 2 weeks ago as my turbo went.
