My 2018 just turned over 5100 miles. Lots of city driving so MPG is only 20.5. I'm taking it to the dealer for an oil change soon. My truck has none of these lag issues once warmed up. Great power, 27-28 mpg on the autobahn. I'm going to ask the service manager if the warranty will be voided if I install a by-pass filtration system. I'd love to do the SKT but being in CA means that will eventually come back on me. I'll just roll the dice and hope it goes lots of miles before it blows up. Not my first diesel. I had a '74 Dodge D250 Club cab I built with a turbo'ed 1964 Perkins 6 banger that blew black smoke like a locomotive and got 25 mpg. I ran it 130,000 before selling it.
That is confusing and complicated looking. Could you explain!As long you keep it separate NO warranty would violated.View attachment 2447

Any modification you make to the emission systems voids the warranty. It's clearly stated as such under the warranty provisions. There are federal emission statutes that also can result in criminal prosecutions to someone that modifies (or assists in modifying) a factory emission control system on a vehicle. This is where it gets complicated. The owner of the vehicle has more leeway in what he or she can do to the vehicle if they themselves make the modifications to the vehicle. Also, you have 50 states whose individual laws come into play and the state law can give you more protection than what the federal law allows for. For example, Texas may not care what you do to modify your vehicle's emissions, probably not the same in California. There, you're probably looking at a long state prison sentence if they find out that you did something to your emissions system.
