Throttle pump settings

Howdy all,
Just wondering what all you guys are running as far as throttle pump settings go? ie, what are some of the values you have for the various settings...

I'm a bit stumped on what they all do even!

pump1 does up to 2000 rpm and pump 2 above 2000rpm, refer to the manual to what the other settings do, they are pretty complex, the standard settings are pretty close to right

most mazdas will only need a few % on pump1 and i think mine are 20% on pump2,

at the other end of the scale my ski boat requires 35% on pump1 and 50% on pump2 to get smooth take offs.

I'd have to check mine, I turned down the pump2 setting from the base map, I was getting some "hiccups" during accel...checked the log that I was making at the time and the pump2 reference was showing up at the same time as the "hiccups". Took some of the added value out and it smoothed things out a bit.

pump1 is +5
pump2 is +22
pump2 comes on at 2000RPM
%stage is 75

Those settings seem to have my car running pretty good. I have bigger 2ndaries, which is why my %stage is at 75. If you still have all 4 550's, then I'd say 50-55.
