Why are you running 17psi on stock injectors without a logger? If you had a logger (which you should if you run 17psi on stock injectors) you could check your IDC and see if you've maxed out your injectors. Sure, you put in a 255 and AFPR (assume you got base fuel pressure straightened out by now?), but you still have the stock injectors. They only flow so much fuel when open all the time, and if you go past that, you can't open them any longer than always, right? So spend $25 and get a used Palm, ADLD interface, and free logging software and find out if you're lean at 17psi on stock injectors.
