[QUOTE="dieseljosh07, post: 850059, member: 122"] Yes, the smaller parameter is why code P0088 sets with Spartan and not the H&S and that code results in the PCM going into derate mode. Monitoring fuel rail pressure and fuel pressure control valve duty cycle under hard acceleration would confirm the control valve sticking open and causing sustained high fuel rail pressure. The same conditions with each tuner giving different results shows the difference in fuel rail pressure parameters. Again, I'm not biased to either tuner, however it's important to remember that ford increased this parameter only for the sake of decreasing the number of HPFP's being replaced under warranty. Customer satisfaction and performance are not there primary concerns. [/QUOTE]
