Can someone give me the formula/ math/ exact number in order to properly tune my FPR for my turbo. I’ve seen people say 45 psi but that’s for stock 420a, and if I am supposed to be running 45 psi can someone confirm that ?Putting on a bigger turbo then the one shown in picture this afternoon...

I have a 97 Mitsubishi Eclipse GS with a turbo kit on it from the previous owner, it’s had tons of money dumped into it but I don’t want to run it until it’s been serviced and with an aftermarket ecu since the stock ecu is still in the car with a “split second voltage clamp” wired in, my friend...
