Sorry to be non ECM, but this injector thread is interesting. I am planning on putting SVO 30# in my modified TPI 355. Some have said that an adjustable fuel pressure regualtor is a valuable tuning tool while others say it causes more problems than it's worth. Also, most people on the corvette forum use it to universally richen or lean, which I can do in the eprom in at certain rpms and loads instead of universally. So, is it worth my $70 and effort? Thanks.
Usually, An adjustable regulator is used for those with no access to reprogramming eproms, and to globally richen/lean the motor due to breathing changes, or injector changes. It can be a hassle, because you burn a chip, adjust FP, now, which change ) (FP or CODE) affected the results? Both did, and you can fight yourself forever and get nowhere... If the stock injectors have run out of flow at stock pressure for your app, a higher pressure regulator can help bandaid the situation...
