If you buy a programmer or install an inline brake, correct?
Not saying that’s a bad option. Installed one on my 07 Dodge because no exhaust braking from the factory.
But that’s a $600-1500 add to get that performance out of the early 6.7 Powerstrokes.
Add that to a persons budget comparison if planning to use the truck in applications where it would be needed or desired.
And based on the simplistic nature of the OPs question, doesn’t seem like a gearhead that would be interested in modding his truck.
(Or wouldn’t have asked about buying a warranty on an old truck)
