while it is not that much i was accually impressed. i wasnt at first. i was like giving it a little more gas than i thought i needed.(had no clue how much it weighed) then he said any where from 8000-9000 pounds i was like oh! ok that explains a little. braking power was increadable. stoped like nothing. pulling power it never once went over 2000 rpms unless i put it in tow/haul( once to see if it made a differnce) and while it did pull harder and easier i would not recomend it unless you are in big hills and need that extra rpm's. while i climbed some long steep hills (but nothing took crazzy) i never went over 2000 rpm's like i said and it held 40 mph no problem. i saw the guy behind me down shift going up the hill (his truck jumped)


over all impression pulls way better than the 98 cummins and the 2001 7.3. and the 03 hemi 2500. i got all first hand experences with these trucks the 7.3 the most. and i am 100% satified with this stock truck with 2100 miles on it.Edited by: yamahagrizzly
