I have a 2000 f250 automatic 7.3. The truck has 200,000 miles. The mods include: 6637 intake, straight pipe exhaust, and now a php hydra.
The issue I’m having only happens when the hydra is installed on the truck. When putting the engine under a load (~2000 rpm) for more than about 5 seconds and letting off the throttle the truck begins to “miss” or search for idle. The longer the truck is under a load and the higher the rpm the worse this issue gets. It will stall out sometimes while searching for idle. I have noticed when the truck is searching for idle I notice the dash lights dimming and getting brighter as it is searching.
I can not make the truck repeat this issue in the stock setting.
What I have done this far: First I contacted PHP, and the chip was sent in and tested good. I have installed a known good IPR, good ICP, new batteries, new alternator, cleaned both the EBPV sensor, tube, and connection points on the the truck. The truck was hooked up to a snap on scan tool and the only code was a P0476 Exhaust Pressure Control Valve Perform.
Anyone ever have this issue or know what it might be? Thanks
