Do I Need an FPR with my turbo setup???

[dsm77]

Im getting my setup installed soon and need to know if I need a FPR with only running 6psi on a 420a 1999 engine?? The place installing it said just the S-AFC will do but I figured you guys on here know better about my motor. Hopefully I will have it boosted soon.

I dont have much info on the 420a fuel set-up. But make sure you search about your fuel setup, if its capable of pushing more fuel than stock then it should be fine, becuase the S-AFC will just increase the amount of fuel injected to compensate for the lean. Make sure you dont go beyond, although it would be recomendable to get your fuel set up just for precautions.


Good luck!
