[QUOTE="Justin@DP-Tuner, post: 1371910, member: 1413"] A good way to test this is to hook up a scan tool and watch ICP and IPR duty cycle. Normally, tuners call for 2600+ psi ICP. If you see ICP drop below comanded and IPR duty cycle go over 65%, that is why you are getting a P1211. If could be caused from a weak pump, or too much PW in the tune, or even a combination of both.
