[QUOTE="ramsing, post: 484995, member: 4754"] i meant getting the stock ecu to be tuned. problem is, as bundy mentioned, is getting a competent tuner. i heard SG has one which has done some s/c bmws. running a piggy back with extra injector is not the most optimum solution. bypassing the ecu might trigger safety cuts by the ecu, like going in limp mode etc. not sure how the system runs in M54s. 250hp is not the issue, but running a turbo where the tq comes in early might need some work on the ignition, not only fueling. u might escape with supercharging though [/QUOTE]
