    No, they are not the same. Diesels have their torque and hp curves peaking way below gas engines. Diesels also don't rev as high over all. So, diesel converters stall around 700-800 (or so I'm told for 6.2/6.5) and most gas burners like a stall more around 1200+ depending on vehicle, weight, gears, and engine.

    Me, I'm running the diesel converter. I don't care about playing "hot rod" and it lets me work through the rocks just a little above idle. I don't have to rev up to bring in the converter while generating heat in the engine and slipping the trans at higher rpms creating even more heat. I still have more power than most jeeps, toys, etc. and it works well for me. However, I would NOT want it on a daily driver, and probably not on a dual purpose rig.
