fuel pressure

[i8av8]

where should fuel pressure be? im at 39psi. in idle and i'm not stock. cam, larger valves, bigger turbo, afpr, large ic, vortec heads, chipped, headers, 255 walb. fuel pump, bbk tb and some other things incase all that makes a difference. trying to chase down a gremlin. tia!

Re: fuel pressure

It just depends on the chip and the injectors you have. If you have stock injuectors I would be at least 50psi if not higher. Some people have even pushed it too 60 to 65psi with the vaccum line in pluged on the stock injectors.

You need to get datamaster or Turnerpro to see your duty cycle and also what the knock counts are.

sorry, i forgot to mention that i have the green 50#'rs. as for the chip...i can't seem to remember right now. it does have vortec on there, though. it is an older style/program.

Re: fuel pressure

you really need something to monitor what everything is doing.

If you want to start to tune yourself I would look in code 59.
