set the fuel pressure then fiddle with the timing, are you running nitrous?

Set the fuel pressure with the vacuum port removed and plugged, plug it back in when done.

Use an adjustable timing lite to set the timing around 14 degrees advance with the plug pulled from the yellow wire coming from the distributor. plug the pin back in when your done.

What should I set my fuel pressure on a mildly built 306, Accufab told me 30, should I go higher? My timing is set at 14-15*.

With 19 lb injectors, 40 PSI with the vacuum port off is about right (that is close to 32 PSI with the vacuum port on at idle).

I'm running 24# injectors.

Maybe 36-38 PSI with the vaccum port off. Play around with it a little bit and see what PSI the car runs the best at. When I bought my 89 the fuel pressure was set at 45 PSI @ 0 vacuum and it ran like ****. Turning it down to 35 PSI made a world of difference. If you can't notice a difference, then just shoot for the middle of the range.

I just sold my 90 lx with a 342 in it. I had the timing at 17 degrees and it ran like a rapped ape. It went a best of 12.40 @ 111 on the motor.Don`t remember what the fuel pressure was though,sorry.

Me too. 100 slated for production. $80,000 each. I'd really like one in Lizstick Red. Or maybe SpeedLab Yellow. :D
