I'm running an aftermarket tank on a custom RC390 with an external adjustable fuel pump and regulator. I'm running the pressure at 50psi right now because I had read that was stock but I just stumbled upon something that said 2.7 bar which equates to about 39psi. So I was hoping someone on here could clear that up for me. What PSI should I have my regulator set to.

~K&N pod filter
~handmade exhaust w/ Lossa Engineering muffler
~1,000ft elevation
~PCV
~Wide Band 2
