I have a 04 f-150 2 wheel drive 5.4 liter. I have replaced 2 cam phasers, Power streering pump, front brakes and tires in less than 32000 miles, but my qustion is to all those peaple running diablo what kind of changes have you made to the tune ? I use it to tow a 30 ft traveltrailer 6500lb and a daily driver and put about 800 to 1000 miles a week.

 

Diablo should be like the rest of the tuners, you have options you can dial in. The best I can recommend is to log and try every option. Figure out what you like andwhat you don't.
