Do a little tuning on the diesel and then there is no comparison,none, notta. And yes it will hold up to it with no problems.
I didn't think I would have ever said this but I MISS MY 6.0! My service truck is down right now so I am driving a truck that is a little lighter and also has a gas 5.4 and I'm telling you it sux! It will not hold OD @ 75 MPH on the interstate. It also will not hold OD on the two lanes I drive around here. I do have to admit though, it sounds good, but it sounds like I'm racing at every stoplight.:S
