I installed a cobra intake before I put my car in storage last november. At the sam time I changed my injectors to 24 and I put in a PMAS MAF calibrated to 24. Just wanted to know what I should set my fuel pressure to? Also, you set it with vac off right? My pressure is currently 40 vac off.

leave it stock.

The eec uses the FP and thinks its at a "point" and known...if you go messing with it then that "point" is off.

since your using a MAF that is already "fooling" the eec, you realy should not go and fool it anymore...get what I am saying.

A good tune will leave the FP stock and adj. the fuel tables/MAF transfer (that even with your "fooled" maf would be a good idea). In all reality if you need more fuel...get a bigger inj. so your not going too high on the duty cycle/Pusle Width of the inj.
