i hate to say it but you won't get any pitty from me. i do ford diesel work
you do that kind of **** to a diesel truck you better be prepared to pay for the worst. whether it's your fault or not it's still your responsibility to know what's going on. i wouldn't trust any dealership to be able to accommodate a modified truck properly, you found that out the hard way
don't get me wrong. i 100% appreciate/respect the kind of power these things put out, you just gotta realize what you're getting into when you play with them
