set fuel press

[crazygn]

OK guys i have my fuel press set at 32psi with vac line on i have 40lb red stripe injectors now does this matter where i set it now will they put out more fuel at 32psi then the stock injectors. It seems like when i rev it it sucks to much air and trys to die. My O2S MV's are mid 250's at idle does this sound good or to high the metter that i have only go's to 400 it does peek that when i rev it a little.what is a good starting piont for my fuel press.


thank

Idle O2's mean nothing. They should jump all over the place. Get some WOT O2 readings. I would start higher just to be safe.

34-36psi sound good ,dont have a scan tool so i cant tel how rich or lean its running as soon as i change to the 87 ecm that i have,a scan tool is the next thing for sure.

thanks for the help
