The dealer may be right when saying it's overspun, but wrong as hell by saying the MBC caused it. I feel the most likely cause for an overspun stock turbo is one hell of a boost leak and a turbine spinning like mad to achieve pressure at the WGA, in 3rd, perhaps 4th or 5th.Originally Posted by nicka117
They said it had been over-spun, and the Mitsubishi rep was there and said my manual boost control was the culprit, especially since they never have problems with their turbos. No warranty coverage and $2500 to replace. Can be a number of other factory related components as well, but that first mod, even just one, will allways be the cause through the dealers eyes.
