Me personally, I'm not worried about blowing coal, making more noise or being first off the line, I'm looking for the mileage gain. That being said, I'm more then happy to remove the DPF, put the delete pipe on and program for the best mileage and have the same power output if that's what was available. So I'm definitely not going to be looking at the 250 for a long time if at all.
My opinion, the things plenty powerful already, but that's just my opinion.
