Default 62 psi Fuel Pressure after Racetronix pump and harness upgrade

So I just installed my Racetronix pump and harness upgrade yesterday. I checked my fuel pressure afer the install using a mechanical guage hooked to the rail and I now have 62 psi of fuel pressure. I am guessing this is because of the bigger pump and the upgraded harness so now the pump is seeing more voltage. Is this normal to see a bump in fuel pressure after this upgrade?

Mine went to 62-63 psi as well after the Racetronix install.

Cool, I am guessing this is normal then. One more question. When you first started the car did it idle low or act like it was going to die at all for the first minute or two? Mine did this when I first started it for the first minute or two then it was fine. I did have the battery unhooked for like a week during the install though so maybe it was related to that. It all seems just great now though.

Might want to change your IFR to account for the change in pressure.

Yeah, I might do this. I need a WB so bad so I can tell whats going on with my AFR. Thanks for the advice.

Your car idled strangely because the battery was disconnected.

The factory computer will learn the idle trim to correct for the additional pressure... no need to retune.

Under load it should come back down to 58psi.
