just had series 2 3800 rebuilt and wondering if an intercooler would be my safest next purchase, I have installed ZZperformance larger throttle body with spacer, Pacesetter headers onto stock exaust, haven't done a fenderwell or CAI yet and I guess that should be next. also installed colder plugs, and had a ZZperformance PCM but I am rethinking that after engine blown..... have a 3.5 pulley on as of now, and still had some KR at kickdown.... any advice welcome thanks, Justin
