That's do-able. I can live with 45mph on a 6-7. I didn't have any trouble keeping my 60 mph cruising speed on 4%. Well, the engine was roaring but I kinda like the sound.
BTW: When one compares 2 different engines with the same HP and different torques, there is an assumption that both units are optimally geared for the desired speed. If not then all bets are off.
Also something else to keep in mind, as one hits high altitudes, a turbo is able to compensate for the lack of air density by just cramming more air in. If not for the turbo, a diesel would be much worse than gas at high altitudes. I'm waiting for a large format turbocharged gas truck engine. Gas engines run hot, so that is the real difficulty running a turbo on a heavy duty gas engine.
I disagree with the "gas engines run hot" I've never hit 200 degrees, average 190, which I think is close to norm for a diesel too.
