Yes Spartan has some serious tunes out for the 6.4, 200hp, 250hp, and a new 275hp tune I believe.

Most 6.4 owners who take the DPF off of their trucks and run a straight through exhaust with a tune and intake are seeing deffinate increases in MPG over factory. They are also seeing over 500rwhp and 1000rwtq on the dyno with these tunes.

Hope this helps and of course this all voids the warranty lol.

I believe the numbers for the 275 tune were 524rwhp and 1,178rwtq

Anybody bother to read the TSB in question? If so, explain how any of the modification contained within could possibly affect mileage.
