Fuel pressure for 85 T-Type?

Hi, could anyone tell me what the fuel pressure should be for an 85 T-type? I'm having major detonation problems and a serios lack of power. I'm getting 30psi at idle and 38 with the vacuum line off. Any help would be greatly appreciated!

Set it to what ever it likes. If you have a 255 lph pump I would set it at 42psi, as mentioned above. If you have a smaller pump you might have to go to 50 psi. Best is to get a scan tool and figure out if its a fuel pressure problem or and octane problem.
