I need to how to adjust it and where it should be for about 10-12psi

You say Diablosport software in your other post about this , your tuner should have all that info to raise the fuel psi with the software , Idealy you want 1psi fuel psi for each psi boost with 39-42 psi as the base so 10psi idealy you want 52+/-psi , 12psi = 52+/- psi

Yup, all in the tune bud.

Tom, he is trying to use a Diablo "chip" (not a flasher) with his SVT ECU.... his tuner should also know better about that as well.

Why is he worried about the fuel psi if the tuner can even tune it then ?
