No, a tuner can tell you how much pressure you are running, but it can't adjust it. Just get a fuel pressure regulator. That's the cheapest way to bump up fuel presure

Default RE: fuel pressure

Depends, at idle i see 40PSI at the rails. You will see more as throttle opens.

May I ask why you feel the need to modify your fuel pressure?
