bc it's operating at lower rpms where its tuned to get peak HP and torque at a lower rpm ,
where the fuel injection settings are tuned at peak.
Super Duty chassis with the 7.3 engine is tuned to produce 430 hp at 5,500 rpm. The Premium RV 7.3 is tuned to produce 350 hp at 3,750 rpm.
I think its better suited for the rv which is always hauling its weight where a P/u is not. To have power early on , lower rpm's, is a benefit in an rv.
Hmmm ... other than in drag, or closed course, racing ... what pickup driver (or RV driver) revs their 7.3 V8 to 5,500 rpm?
I'm guessing that the "RV tuned version" of the 7.3 V8 would probably be putting out close to 430 hp too ... at 5,500 rpm.

Realistically, how many people drop $70-90k on a truck and go around with it floored at 5,500rpm with a heavy load.
