    high idle

    I just put a 3,800 stall in the goat. 220/224 .570/.580 112lsa cam. I have my idle set at 775 rpms, it idle good anf stays there but in gear and moving it wants to idle all the way up to 1300+ rpms.....throttle cracker is zeroed out. am I missing something? IAC is sitting at 10-12 ° when idling at 775, would cranking the idle stop set screw closed alittle fix this or is it in the tune?

    Adjust it so that the blade closes some. Look for 55-75 steps at hot idle. Once you do this, you will want to re-do your idle airflow tuning. Additionally, while you may get by with the TC table zero'd out, I like to add 1.5-1.7g in the 400 RPM column everywhere except 0 MPH as a kind of a 'catch' in case you ever have a big dip while moving. It is helpful when beginning tuning and definitely can't hurt to leave in there.
