Well, it definitely gave me a 1 mpg increase on my 07 5.9. I just wish I could claim the same with this truck......

 

I have read one post that said they may have found traces of a Smarty. It was from a person who worked for Dodge and was looking for traces of it on a truck he knew that had one on it and was taken off.

 

Yeah, thats still not credible IMHO...

 

I agree and I'm definitely not bashing the Smarty. Everybody here that knows me knows that I will eventually have something on my truck regardless of what my sig says. When the time comes I am sure it will be a Smarty, especially if it brings my mileage up......

 

Any more info on this?

 

Mileage is still exactly the same and I "think" I may have a tiny bit of extra power off the line. Other then that I have seen no gains with it. I wouldn't waste the money on it........

 

burn outs are way easy with the 6.7. Just do A very small power brake just enongh to get them to spin set the auto trany in 3rd gear and leter rip. How long of A sratch you want dependes on how long you hold the go pedal.

 

Anything more on this? Just would like a bit more.

 

No gains to report in mileage or additional power other than that tiny bit of power of the line. If you already have one laying around then put it on. I would not buy one if you don't already have one....
I was going to modify this one to try and get more timing out of it but have not done so yet. Honestly, it just slipped my mind.....
