Does anyone know if the 350/800 cummins is the same as the 350/650 with just a diff. factory ECU flash?

Yes it is all in the software. It depends on body style (cab and chassis, 1 ton, etc) and most importantly what trans is behind the engine. The Aisin trans equipped chassis get the big tune.

Are you sure about this? It shows on the website that the 2500,3500 with auto make 350/800 and the chassis cabs with the Aisan trans only make 305/610

68RFE used in 350/800 applications in pick-ups. Aisin transmissions are put in C&C trucks.
