So I installed a Walbro 255lph (High pressure version) on my stock engine as i will be boostin soon. Problem is that i don't think my FPR can handle it because at Idle I am running pig rich like 10's or 11's A/F. Can i do anything in Uberdata to correct this or do I have to get a new FPR. I tried upping the fuel pressure in the misc tab to 50 and 55 psi instead of stock 42, It seems a little better but then my 02 device displays "lean" when I'm at WOT or high rpms.

Should I just street tune the whole car now so I don't run pig rich or is there another solution. Have other people had this problem?
