How to adjust base idle effectively?

Used only on the 03/04 Marauder but can be used on any 03/04 ecu with code changes. Uses newer style SCP array so will not control cluster correctly on 2004 and older fords that use the older style SCP array such as mustangs.

I am wondering how to bump idle effectively… I can change Neutral Base and Drive Base values but it seems like idle spark or something else needs a tweak. Can Someone please tell me how to do this properly? Thanks
