I recently had a drag turbo kit installed on my 01 lude. It was running fine, then all of a sudden i was driving on the freeway and, now i cant make boost. At wider throttle postions the car has no power it seems like. Could this be due to a problem with my fuel system? Also, does the timing of my engine have to be retarded or advanced or something?i Had my timing retarded when i had my cam gears put on a while back,does it have to be redone?
