me and 1 of the level 2 students at work have fitted a supercharger to his bmw, its all running and idle ok but it seams to be running a lot of boost and its not controllable, we have got a recurculating dv on it but the return it left open to the atmosphere when connected it wont run and all the pipes expand alot, any ideas, re-map, butterfly, bigger pully?
