I know nothing about the fords, i just know i sold a old style evolution to a buddy in his 01 ford 7.3, i basicly got that one because of the price. He loaded up the 100hp tune and he is very happy with it. Comming home from the races last week with my 04.5 trailer in tow with my 4k+ race truck on it, i ran a ford 3/4T with a 7.3 and some sort of tuner loaded up to the max he said, of course he was an empty truck and i had a trailer and still out ran him. We ran from 60 to 118 where mine shuts off, we stayed side by side till prob. 80mph then that cummins came alive on him... but when mine stopped at 118 quess what here comes the ford.. it will run faster on the top, more rpms not more power...
