Professsional Product FPR and -6an lines. FP at 40 psi ok??

[Hmong_1G]

Hey guys. Well I decided to add a FPR and -6an lines to help the walbro from whining too much. After everything was done I end up bypassing the BVSV for the stock FPR and run it straight. The FPR is a Professional Product part number pfs-10671 . http://www.summitracing.com/parts/PFS-10671. Its look great but my Fuel Pressure is at 45 psi without vacumm attached. With vacumm its at 40 psi. Sounds logical? Please any input would help. I just have the basic bolt-ons and running the factory 440cc and stock turbo.

well assuming a healthy engine it would pull approx 18-20INHG of vacuum, this converts to 9-10PSI vacuum. Pressure should change that amount with and without vacuum. The stock spec for a GTE is 33-40PSI (IIRC) with no vacuum.

If your running 440cc injectors and a stock AFM, adjust the fuel pressure untill the VF voltage is steadily ~2.5 volts. When that is complete you know the TCCS is happy with the mixture and therefore the fuel pressure should be correct.

Excuse any typos or hard to read thoughts, Im slightly inebriated.
