Advice?? fresh rebuild on 02 Bonneville SSEi

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

Justin,

I'd rethink that PCM as well. A few guys here have had issues wtih their pcms. Coming from the Bonneville world myself, they didn't have the best repuation for pcm's on Bonnies either.

Step one, remove the TB spacer, it's only a coolant leak waiting to happen.
Three change that pulley to a 3.6 or toss in a cam/rockers
Two get a fenderwell or intake of some sort.

See..I really wanted to renumber..I just didn't.
