Jim Testa 104 Chip *HELP*

[86BGN]

What is the recommended fuel pressure for a Jim Testa 93 and 104 chip for 009 injectors? I have no idea, so please help! I have the 104 chip in now and with DIY alky on the scanmaster my lowest o2 shows 855 no knock, that is with 45 PSI fuel pressure at idle and 22 PSI of boost with the alky using a .28 jet size. That seems rich.

Thanks

streetchip should be somewhere in between 38 and 41 pounds.not sure about his racechip though. try lowering fuel pressure a pound at a time til you are were you want to be with your o2 readings.

Thanks for the reply, does anyone know if there is some kind of spec sheet on his chips?
