Im trying a new tuneup this weekend on a ST 2 stage diffuser. turning it into a single stage with a progressive. Im using a 82n 73f in both ports. I have 2 regulators 1 for each fuel solenoid. What fuel pressure should I start at?

Is this on a SBF? Better watch all the plugs close and keep it conservative. That will be like 550hp throug a plate.

I run a single difuser plate and with those jets I run 5.5 PSI with 950/975 on the bottle.
