Switching ECU/EFI system on Blown Big Block

Looking to switch from a Megasquirt fuel management system running Tuner Studio software to maybe a Holley system (Terminator-X w/Hyper Spark?) Looking for a knowledgeable vintage tuner that understands a blower (871), inter cooler, Mallory, MSD, etc. type engine... (if your 23 and own a S2000 Honda... no need to apply) Thx for your time...
