Galaxy clogged up turbo vanes, Fixing options?

[The_Burg]

Hmm, sounded very different on Shell Nitro and a couple of cans of Forte. Seemed to run very well. Then limp mode, reset and limp on a touch of throttle. Recorded boost with Torque, nothing seemed amiss. No codes recorded either. Only 100 miles so far so maybe it will work? I suspect not. Not much left to replace except the turbo itself.
