having an integrator delay a bit on the long side doesn't really seem to hurt anything.

As to your comment about feeling "held back", I have also noticed the throttle response isn't quite as crisp as it was when running SD. But if my splits never come back I'll deal with it.
that's typical. the map sensor, tps, and everything else other than the maf responds damn near instantly. ve can tend to provide a natural accelerator pump effect, since vacuum often drops then recovers from quick throttle movements. the maf on the other hand, has a bit of a delay. i think it uses tps to try to account for it (i think kur4o was working on trying to tune that).
