Default Supercharger/Fuel Pressure/Tune help

Finally figured out that my SCT mailorder Chip from JMS was screwing my car up and would not allow it to run right...I pulled the damn chip and the car idled and ran almost right for the first time in 2 months.

It is getting tuned next Friday, but I want to put a few more miles on the new set up...my Air Fuel Meter is reading in the Stoich zone towards the lean side...can I bump my Fuel Pressure up a few points to richen it up?

If so how much..it is at 39lbs withvacuum offnow. Thanks
