That is why the stillen kits clack away like a tap dancing festival once they are heat soaked and the ecu starts pulling gobs of timing as the knock sensor pick it up.

I didnt think of the supercharger situation with the "suck through" maf. I was thinking only of the Turbo setup with the Mafs in their stock locations. But your right if the Maf is upstream of the FI setup (turbo or supercharger). The fix to that problem is just to move the MAFs to right before the throttle bodies. Then you can deal with it in much the same way we do with the turbo kits.
So yes your right didn't think of that condition during my reply but its an easy fix that would make that kit much easier to tune.
I was thinking more along the lines of a 5-10F increase as the metered air enters the heat soaked plenum.
