Most of the issues seam to have related to piston #5 / #6 as a result of heat & detonation. There has also been a few reports of bearing failures on those pistons as well. Main area of turbo failure, and it's not really the turbo itself, is due to waste-gate rattle &/or seizure. Have not seen any reports I can recall of actual turbine failure on the n54 but I'm sure there would have been.
CPS offsetting is what the Procede does to allow it to influence timing, flashes if they are done properly adjust the actual timing maps on the ECU.
