Dual Stage MBC???? & FPR

[4g63telantra]

I have a AEM UFPR that Ill set to 40psi of fuel stock. If I was to run 15psi of fuel, Il have to have the FPR set as 55psi.

Just wanted to know If i have the Dual Stage MBC set at 15psi and 25psi, Will the FPR go to 65psi on its own when I get the button on the Dual Stage MBC for 25psi of boost? or will it sit at 55psi?

Or does the FPR add the fuel pressure when I add PSI of bosst?

You answered your own question. The AEM is set at Xpsi (stock is 37) and then as you hit positive boost, you will add +1psi for every 1psi of boost.

So at 15psi boost and the AEM set up for 37psi, you will be at 52psi fuel pressure. When you use the 2nd setting on the 2stage MBC, you will be at 62psi.
