zd30 common rail severe lose of power very hard to start

Also rang dp and they said its impossible for that to happen, now i replaced the ecu i plugged the dp chip back in and i have a green light and hasnt fried my new ecu. But im taking it off and gonna get a proper dyno tune. So if anybody wants a dp chip for common rail zd30 its up for grabs. $550

Hi you said you replaced your fuel filter every 10k thats an expensive exercise, you'll get at least 40-50k out of genuine filters.
