93 cobra with Vortech supercharger correct fuel pressure 42 PSI??

[Brenna23]

What is the correct fuel pressure for the 93 Cobra with a Vortech V1 supercharger ? I'm told 42 psi with the vacuum line off the regulator?

39-42 is acceptable

The answer depends on the specific injectors you have as they are rated at different pressures and have different slopes, breakpoints, and voltage offsets... then, it really is in the tune. Ultimately with tuning, you’ll be fine at any pressure as long as you fundamentally have the amount of fuel you need and have ideal parameters plugged in.
