MAF tunning for 110 degree LSA

What settings will I have to modify in order for my MAF TPI setup to work with a 110* LSA cam? The cam is a comp cams xtreme energy 268H, 224/230 * of duration @.050 and .470/.480 lift. It's in a 355, 9.5:1 compression, fully ported and polished 487 casting heads with 2.02/1.60 manley undercut valves. I'm using a stock 85 vette TPI setup, that I will upgrade to use the 86-89 ecm. I'm modifying an 89 F-body BIN file using WinBin. I've heard that the idle quality will be poor with the 110* LSA, just curious what values need to be played with. I've already upped the idle RPM and lowered the fan temps, plus deleted VATS and EGR, I just want to start with something that will safely and reliably run the engine. Should I modify anything else before I try the PROM?Thanks for any help.
