Have a 2004 Dodge Ram 2500 with cummins diesel. Recently installed EDGE performance chip. Chip malfunctioned and wasn't showing any status on its screen. Chip was removed and returned. Not too long after, truck starts fine however just stalls/shuts down even at highway speeds. Truck then takes a few minutesbefore it restarts. Check engine light came on. Reads codes PO201 injector #1 control circuit fires improperly, PO234 turbo boost limit exceeded, PO148 high pressure common rail errorand PO628 fuel lift pump circuit low voltage. Looking to install FASS system to override the stock lift pump? Any help would be greatly appreciated. Tony

 

I would start by making sure all your connectors are tight, clean, and fully seated.

 

Three differentedge dealers in Reno told my wife that they quit selling edges because out of the last couple of batches they got all the ones they installed the trucks had come back with some major problems after the install.

 

Anyone figure this out? My 2004 ram 2500 hemi will drop rpm to about 500 then pick up and drop from about 1000 rpm to like 200 rpm then stall. Only happen when slowing down or stopping. It has a brand new throttle body, new crank sensor, new evaporation leak detection canister as well. It’s catless with a 40s series muffler. I’ve changed all 4 oxygen sensors. What will it be???
