Working on my project late 99 auto f250. Had a Dpc-401 (manual) when I bought it for some reason. I would love a DPC-422 for the upgraded programming I've read about but everyone is too proud of those for my pockets. I've found several 2000/2001 DPC-425's from E-350/E-450 vans for cheap (same 7.3 and auto). Will these work at all? with no side afects? and have the benefits of the 422's? Any insight would awsome.
