pretty much sums it up. we had a guy running stacked edge and bully dog chips..with an afe cold air intake, 5" downpipe..straight pipe out, gauges, FASS system...etc etc. it had a bad injector o-ring..we replaced it. 2 weeks later he has a claim of fuel in oil smell, we check er out, found a cracked injector nozzle. we replaced it..under close paperwork from chrysler...this went on and on...then he bought some 100hp injectors, we stuck them in. 3 months later, he gets it towed in, oil pouring out of the dipstick..well, his new fancy injectors nozzles broke/melted off due to HIGH egt's. being the guy our service manager was...he tried to buddy buddy deal him a new engine under warranty. little did he know, when a cummins breaks to the point of needing a 7k dollar long block..they send some reps out to scan the truck and look at it. one word...******. exactly what he was. they wrote the vin down, punched it into the system and flagged it"WARRANTY VOID FOR TAMPERING. EMMISIONS WARRANTY VOID FOR TAMPERING. BUMPER TO BUMPER WARRANTY VOID FOR TAMPERING" needless to say, he paid dearly for the power the truck really didnt need. they have stout engines stock. theres NOTHING you cant pull within the recommended capacity of these trucks.
oh..btw..7k was dealer cost...not customer cost..no labor included either.
