I was at ~12.2 AFRs at redline on an S14 SR with OEM ECU, Injectors, MAFS and Turbo @ 12.66 PSI.

Made 273WHP and 280WTQ.

I recommend running 8~10 PSI and upgrade your setup to support 14 PSI. However I felt that nearly 13 PSI was safe given you have similar AFRs to mine, starting out at 10.8 and leaning out to 12.2.
