The only thing that is important is that you know what the injector flows at your new pressure. There are a couple of ways to do this, either using a mathematical formula to figure what it SHOULD flow, or, have one of your injectors flow tested at the new pressure.

Are you in agreement that 60 lbs of pressure will offer better performance/fuel burning than 45 lbs.? My plan is to run 4 back to back runs Fri night. Two at current 45 lbs. pressure then change to 60, change fuel pressure in software and make two passes to see if it makes any noticeable change in performance. Thanks.
