Did the wiring convertion on my 87. It has a LB3, Areomotive FPR,Brown tops,Big Vam. Know the turbo is not on the car yet[waiting to put the motor in the car,to cold]. My problem is when i start to go above 3500 rpm's the danm car starts to PING loud, so loud that my girl can hear it beside her when i pass her on the road. Timing is at 12 degr. btdc and fuel is at 20psi at idle and 26 psi at wot. I did unhook my premium wire thinking it was that but no change. Any thought?

20psi?

You need ~twice that much at idle dude...and it should go up one PSI for each pound of boost as well.

Thats still a low fuel pressure.

guys there is no turbo on the car yet.

Stock fuel pressure at idle with the vacuum line removed from the regulator is ~38psi for turbo and n/a cars (even use the same regulator).
