i second the opinion on lose the hypertech and get a chip ive got an 02 7.3 was running hypertech on the top setting 100hp stacked with a banks 6gun 62hp ditched those and got a chip from jody at dp tuner and on its lowest setting 60hp it flat out smokes what the 2 i had stacked would do on their best day and when i turn it up to the 120 setting and stand on it it breaks the tires lose on the 2nd and 3rd gear shifts and screams has a 140 setting as well and the best part i ebayed the hypertech and the 6gun and that paid for the chip plus had $70 left over and im getting better mileage useing the 80hp econo setting !!
