Ditched the FMU..need a "base" setting

[RBRANDX]

T-trim s/c'd 331, H/C/I, switched to #42 injectors, no more FMU, anyone running a similar combo? I just wanted to see what you have your fuel preessure set at as a "baseline" until I can get this thing on a dyno..I will be driving the car there ( 100 miles ). Thanks.

just set it at 42psi and dont boost untill you get onto the dyno. no matter what you set it at, you cant get into the boost cause the difference between 40psi and 50psi or 60psi at the regulator is no where near enough to handle the fuel needs of a car with a sc.
if you set it to 42 and you stay out of boost, the cars ecu will control the afr with pulse width and vacuum on the reg like it is supposed to
