How to Adjust Fuel Pressure in the tune

How do I change the static fuel pressure in the tune?

C6 corvette, supercharged LS2. Not transferring fuel from one tank to the other due to what im thinking is a lack of fuel pressure (needs 56psi to open the pressure switch on the passenger tank fuel pump/syphon).

Thanks

It's not controlled in the tune at all.

You need the bypass for the passenger tank.

You don't. It's all mechanical on all C6's except ZR1's. There's a regulator in the driver side tank that isn't adjustable.

If you have an external regulator from an aftermarket fuel system then adjust it there.. if not, then something else is going on, it's not a tune issue.
