I have my fuel pressure set at 39psi with the vacuum off.
I know stock setting is between 36 and 38. I didn't know if I could get any gains for the 1/4 mile by increasing or decreasing it.
Does that sound right for my set up or should I increase or decrease?

you want to gain in the 1/4 mile and fuel is not the issue. higher timing will give you a little more. or remove the spout connector before the run. lower tire pressure in the rear higher in the front.

I race every weekend. That is what I use my car for. I already know about tire pressure. My timing is advanced to 15. I don't believe disconnecting the timing spout will give you any horse power gains.
What I wanted to know was if my fuel pressure for drag racing set at 39psi was a good number or should I adjust up or down. Basically getting a better air fuel mixture for racing. That's all .
Do you drag race?
