Ok, anyone got any tips for testing fuel pressure under boost? We're talking a manual trans so I've got to be moving under a load to get a reading right? Run an extended hose around the side of the hood and tape it to the windshield?
Is my best bet to fake the boost with regulated air pressure with the engine running? Or do I jumper the ASD so I'm just testing FP? If the regulator is bad, (new Bosch pump) do I get a rising rate regulator or some other aftermarket setup (are they direct bolt on) or do I go with a stock replacement?
I'm running a 2.5 T2 in a Dakota - boost limit @14 (BoostButton cal/SMEC) I'm running out of umph @10psi, I get a popping from under the hood @ WOT
Someone's suggested valvesprings and they're on the list of things to switch - I'm looking for one more thing to test before yanking the IC piping, VC & such off to swap the springs.
