With modded motors it may make sense to add a bit of decay and possibly increase the PW a bit at the lower Delta MAP. Probably want a bit more fuel going there at smaller Delta MAP since tthe secondaries are not likely to kick in.
Dom,
You're using TunerCat, right? There are probably 500 items not defined in TC's definition files. D-TPS Acceleration Enrichment is among them, constants AND tables. And, as I said, don't think the AE things are all labeled right in TC anyway. I will say that the initial D-TPS AE term is not a traditional table like the MAP AE is, but it is in there nonetheless.

The BMCB is one that I know has the sloped MAP AE values.

This is without a doubt the most frustrating part of any calibration to get right. It's a delicate combination of many factors to get it just right. And lots of trial and error, and trial again.
