Your accel enrich numbers may be very different depending on throttle body, fuel injector size, etc... I have 780's with about 35 psi of static fuel pressure. It's not 43.5, I found that lowering the pressure a tad helps keep the duty cycles up which makes the idle smoother.

I used TPSdot for a while, but these days I'm using MAPdot. Mine look kind of like this:

ms kpa/s
3.2 240
2.4 170
1.4 100
0.8 30
threshold is 30 kpa/sec, duration is 0.3 seconds, decay accel enrichment, 0.0 value at end of accel time

Tuning AE is tricky. These settings seem to be always changing on my setup. You have to be able to hit the same kPa/sec consistently and watch your WB at the same time. It's not easy! To make life more difficult Megatune has a poor interface for tuning this, there is no way to read your exact kPa/second, you have to watch this bar that has a fixed scale from 0 to 300 kPa/second.

If for example you are cruising around 40 kPa and bring it up quickly (within 1 second) to around 100 kPa, you have to watch the wideband and see if it goes rich or lean. Ideally it should go rich a bit from your cruse AFR, maybe to around 13:1 then it should go back into closed loop.
