they are alot of dealers around that dont mind aftermarket stuff. that being said they have regional managers that will throw a fit if they happen to show up with trucks in over night. find you a dealer that dont mind mods and dont tell on them. they are many out there.

 

rumor on the street is that the new Smarty for the 6.7s won't be undetectable anymore.

 

Yes, the smarty is now detectable. The 6.7Ls computers and junk are more advanced.

 

That sucks... the main reason I was holding off on buying a tuner was the abiltiy to go undetected..... and now this bad news

I hope they find a way to get it hidden again, or at least someone does. I don't even care who's tuner I buy, I just don't want to deal with the warrenty being voided for running a 50 hp tune/decent mileage increase in the truck.
