ermmmm, every one of those examples had an adjustable fuel pressure regulator...
I thought this was all about standard injectors with standard rail pressure?
you could probably make 1000hp out of 370cc injectors if you run 300psi rail pressure...
Also Kasko, go the NIStune, easy to use software and does everything thing you need. and if ya need to change something you can just get a retune done locally and your set.
I've got mine running from my sterio (carpc), so i can fill up with e85 and change the tune while sitting at the servo.
