Check the fuel solenoid is not sticking.

If its getting to 30k then the gas is working right!!!!!!! Most motors can only spin up to around 20k I believe, and would think if its sticking it may have been part open explaining the slow acceleration as the pump would be unable to keep up the demand from the flow.

Not sure on the jetcat if you can put a couple of volts across the fuel pump in situ and see if it, well, sucks!!!!

Let us know!
