got some numbers. all these are when hot and on stock mode
highest number when it started that i saw was 1500.
idle between 450 and 500 jumps all over the place onlce saw it at 500 for a secound.
my girl friend was reading the number and when we started to move to get onto the road (normal acceleration) she siad she saw it drop down to 435.

on the road wot hightest it got was 2488 she siad it help it there for the most part. so thats what i got on that.

should the numbers be jumping all over the place like crazy?

450-500 seems a little low at Idle. You should definitely fill out your Sig so that we can see what Mods you have done. If you have stock injectors I would talk to your tuner about bringing ICP up at idle possibly, but its not going to cause the studder.

What has me interested in you saying ICP dropped down to 435 as you put it in gear and started to accelerate. That is not necessarily a bad thing, but it shouldnt happen. Also what were the duty cycle numbers. 2488 at 20-30% DC wouldnt be that bad, however 2488 at 40-50% DC would indicate a problem with the pump.

Post up what your mods are, who does your tuning, and what your DC% is at idle, at WOT, and just cruising down the road.
