I have a friend's MC engined 200 in the shop with an overboost problem. Boost spikes up to 0.75 to 1.0 (0.7 bar spec) and fuel is cut off. No fault codes, and only occurs at kick-down (auto trans, fwd). Any ideas?? I don't have an extra MAC-14 floating around to swap either, so I'm a little lost. Jouko Haapanen Pori, Finland
