I'm upgrading to 440cc gtr injectors. Do I run: A) the standard fpr (Gregorys has the vl base fuel pressure at 250kpa or approx 36psi) B) gtr fpr/aftermarket adjustable (GTR from what I can see is 43psi) to match the injectors. Thanks

Put the 440's in mine with a nistune and it's happily running on 15lb with the standard regulator. Tuned by Jim down at CRD in Rydalmere.
