base fuel

[SFRacingGST]

Stock fuel pressure settings are as follows:
1G=37 psi
2G=43 psi

These readings are taken with the vacuum line off of the AFPR.


Just wondering if a 2g with a 1g block and head should get 37 or 43?

The fuel pressure settings are based on the ECU that's in the car and what it expects to see. Since you're a 2G and have a 2G ECU, the base (with hose off) is 43.5PSI. Although 43 or 44 works fine.
