Your truck should be out of warranty so no problems there I guess.
Does your state do emissions tests?
Stock vehicles have lots of software safety programming so that basically anybody can drive the truck, know nothing about it, and not hurt anything. When you change the software alot of that goes away. You have to understand things like exhaust temperature, transmission slippage, over-fueling, etc. If you know what you're doing, pay attention, and don't try to run more HP than the rest of the truck can handle you might get some more mileage out of it.
