Whats the plan for the car? Stock DD? Mildly modded? Big future mods?
I did 190lph for my 3.0L. IF its a stock DD I'd go 110lph or stock (which I beleive thats what it is.)
just changed the fuel filter
broke it open and it was liquid tar and a black filter
it runs MUCH better, but i don't see how it could change the 12 psi deficit
Having a big restriction will reduce flow and create fuel starvation at high RPM. I actually have the same problem and thought, from the reading I've done, that I had to clean the Upper / Lower intake manifold but I will definitely be changing my filter first.
Just wanted an update man I jumped on to ask this same question... but mine drops off bad at around 5500-5900 to redline. Was not sure if it was the alternator slipping bad, because I also have a bad battery cable and have not had the time to replace it :*(
