Holley Sniper EFI

Yeah Woody was supposed to get back to me after he got back from holidays today, by the time I get the new manifold on he should be back online.
I wasn't able to adjust the idle anymore, I set the timing at 15 deg and the warm idle at 750 rpm, turned off the idle spark control and checked the timing on the crank. Both the crank and the sniper controller are on 15 deg so that is synced, can't get the idle below 850 now. At least the headers aren't glowing now. if I turn the idle spark on it gradually starts pulling timing out and the idle comes down towards the target of 750 rpm, but then the headers start glowing again. I'm thinking there might be a vacuum leak as well somewhere.
