Post by: micka8 on Mar 12, 2009, 08:57PM

It wont matter what pump you use its the fuel pressure regulator that will determine the pressure, 300 kpa sounds about right.

im asking cause i had it dyno yesterday and he said it was running lean, and it seem to go harder with the other pump which was a vdo from bursons that was running my old ca20, anyway getting the nistune put in tomorrow and that should sort it out

Nistune can't adjust your fuel pressure though. You'll need an aftermarket fuel pressure regulator to change anything.

Yeah the nistune wont fix your problem, well you could try to tune around shit fuel pressure. It could be as simple as a blocked fuel filter. Get the fuel pressure and flow checked using a gauge. Most places should have a half decent setup. Fix the fuel system problem before trying to tune af mixtures.

well i got it tune yesterday, just a quick one and he said its running richer now, and it would be better to get more cold air to it. 149 killer wasps now and then i left my 3 month old exedy clutch started to stuff up on me

Fuel pressure should be about 43psi from memory.
