If he has bypassed the MAP signal on the SAFC by re-hooking it back up to stock config ie- map wire directly to ECU then the SAFC is doing nothing NOTHING for tuning. You can change any settings you want on it and it wont do anything. It is now merely a display tool. The only thing the SAFC has the ability to change on our car is to alter the MAP signal and all those settings are in reference to when and how and how much it alters the signal.
that is all.

Not to sound like an ass but...
Sounds like this car and its tuning have gone beyond your ability. You might need to back off playing with it until you understand some more of the fundamentals of tuning and building. If you don't know what SBR did (and it doesnt sound like they have a clue about the 420a) then you might need to step back and find someone who has more tuning ability in your area that can help you get all these basics worked out.
