I have an odb2 gsr with cai/h/e, act clutch and flywheel. I recently installed a fpr and gage and was wondering what psi I should be running at idle and/or under load. I am also running a edelbrock nitrous kit with a 75 shot. I appreciate any suggestions.

 

with the vac line off, prolly like 42-45, that will /should show you what it will be at full throtlle then ,. . . when you put the vac line back on it should go to like 35-38 psi . something like that

 

what ^ said.. depending on if you have a adjustable fpr you can bump up the fp for a little more safety while on the juice.
