Hey Mr.Gris! Thats pretty funny! When you blow the engine in your truck and you need my help to get it covered under the warranty, don't call me. I'll be busy laughing my a$$ off at you!

Sorry.............couldn't help it!

HotDuck,
On the 6.4's most guys are running the Spartan Diesel Tech setup - - DPF delete, 3 custom tunes, Dashdaq for monitoring and claiming up to 6mpg's better stock. I don't have a DPF setup yet, but its tempting. I'm sure there are guys doing to same for the new DMAX.
