You should do some more reading/research before flapping your gums, none of the parts he is pulling off are "warranty voiding" parts, some dealers are just anal, and will try to void warranties for ANY aftermarket parts. Also the problems that he is having, are VERY common with 6.0's, even stock ones, and are not caused by anything he has done to his truck.
and the reason the dealer wants to VOID the warranty is
because he will get paid a lower rate *AND* a reduction in allowed
"HOURS" if worked is performed "under warranty".
so the MECHANIC *AND* the DEALER make more money when
something *IS* *NOT* covered under warranty !
