What is a good fuel pressure for 30 lb injectors? Also, in tunercat what would be the exact injector constant? I had 24 lbs in the car now but they went south so I am temporary installing my 30s in the car to keep it on the road. Thanks, BranZ

 

Standard 43.5 psi is where they should be unless the maker says otherwise for those injectors. 29.45 is what I use for my Accel's I believe, Accel rates them for 29.4 @ 43.5 psi...

Don't forget to tune the VE and PE tables for them...

 

..and the AE..
