fuel pressure
I just got back from the truck trying to be tuned on the Dyno, I found out maybe why it is pretty gutless 5.4L the fuel pressure is only reading 21psi, I'm pretty sure it should be atleast double that, I just ordered a new fuel pump a few mins ago, any word of wisdom? the tank was just filled of course for the dyno date, FML
thanks ahead of time
oh, ps.....I went from 4.6 to 5.4.....the injector are the original ones from the 4.6...(pink) that wouldn't cause the pressure loss would they at the test **** on the fuel rail?
