heads/cam help!! i have an 02 trans am with texas speed stage 2 5.3l heads, .595 .598 cam, headers, bolt ons. Had it dyno tuned and it put down 434 hp and 381 tq. Went to track and went really sluggish. Keeps throwing mass air code and map sensor code. It seems like it doesnt have any power anymore. Any Suggestions??
