43psi base with a raising rate of 1:1.
1 psi boost raises the fuel pressure by 1psi. so if you boosting 10psi your fuel pressure should be 53psi. -------------------- |

yes, but not at idle. your FP should be set with the car NOT running. you have to bridge FP and B+ to turn the fuel pump on, and then adjust it to a BASE pressure of 43. once you start the car, the vac of the motor will change the reading at idle.
