    just recently i have been having my CEL light come on whenever i go over around 70% throttle. as soon as it comes on the engine will overheat, high idle (2000), and horrible throttle response. I think my engine might be goin in limp mode from slight detenation. Any help would be apreciated. I havnt had a chance to see what code im throwing but will shortly , thanks

    first step is to obviously pull the code

    fromt he sounds of it- it sounds liek a map sensor issue.

    what are you suing for management?

    Most likely he is using a missing link or check valves.

    Do you have a boost gauge? If so, what's it reading?

    Your friend is right, you shouldn't need a check valve if you are running the hack, or the original hack using your vafc. I'd take a good hard look at your PCV system. In extreme cases, you can heat soak your radiator in the presence of a fatty FMIC. Hot coolant running through your IAC valve will make your idle get nuts high as your ECU tries to keep your engine from stalling out. Or you could have a failing map sensor :D.
