FiTech EFI system

Mine has been running pretty good but wanted a better idle when dead cold and hot as well as a better start-up when hot. Played with a few settings that I thought were IAC related and made things much worse! Now could not even get it to start last night when hot....:o( Beginning to think this setup is not for me as I am not very techy....:o(
Might see a 600Hp unit and FCC on the add page very soon!
