Looking for some help... something has gone wrong! 02 Cummins, 103k, FASS150, EJWA CTS2 I installed the EJWA about a month ago... did everything myself, install went great, truck ran great. The only problem I had was I didn't think I was getting the full power of the chip from levels 3-5. There was no big difference between the two, and I had read enough and spoken to several people to know that shouldn't be the case. This lead me to buy a BD Stealth plate, which I installed Friday night. Here is where the troubles began... install went great, only problem was the gasket set I bought did not have the two Gaskets for the intake manifold. Therefore I had to reuse the ones that were already on the truck (I had just replaced these about a month ago when I installed the EJWA originally, so they weren't in terrible condition). It was 11pm and I had to move the truck from where it sat. Immediately when I started the truck, I knew it sounded differently. Check engine light came on, and code P1690 appeared. I have a rough idea of this code (Fuel Injection Pump CKP Sensor Does Not Agree With ECM CKP Sensor). Truck had NO throttle response, and sounded awful. Saturday, I picked up the gaskets and installed. Truck ran perfect, check engine light went away, and I finally saw the big power gains from EJWA levels 3-5! The BD Stealth Plate did it's job, and I considered problem gone...figured the truck was sucking air through the used gaskets. This morning, problem came back. Code P1690 present, check engine light back on, and running terrible (rough idle, smells like it's running rich, extra puffs of smoke at idle, no throttle response, etc.). Almost seems as if turbo is not present... just a loud diesel engine. Any suggestions?? Thank you in advance!! Morgan
