did some reasearch, Edgejuice W/attitutde has a lot of options and a turbo cool down phase as well. Not sure what the smarty will be offering once it comes out for the 6.7 but I will wait, before I make a decision.

 

We can not talk about some upgrades here. So I guess EDGE or an MP8. Both work great alone or stacked.

 

why is it that it is split down the middle, smarty/edge. Which would ya'll consider better and why.

 

Edge Juice you don't mess with the computer and can't erase updates you have gotten. Plug in style.

 

what kind of MPG increase is there associated with the edge juice

 

I really wouldn't worry about the muffler. You are not going to notice any difference at all with the junk in front of it. You could get rid of the muffler totally and it would still sound good and not overly loud at all. I have the MBRP replacement muffler on my 04.5 and I wish now that I would have just straight piped it and saved the money. If I were you the first thing I would get if you plan on doing some upgrades would be a set of gauges. Then........the SMARTY and a good air intake.

 

Thought about the guages but if I got Edge W/Attitude all the guages are there. And would just need a good air intake.

I like your style Ive got the same mod for mine as #3

 

you want to know the difference between the edge juice w/attitude and the smarty s67? THE EDGE REALLY DOES EXIST! The smarty is just a myth. Every day is April fools for Marko when he gets on here and reads all the poor schmucks still holding out hope for a smarty s67. IT'S A UNICORN, PEOPLE! FABLED CREATURE!

 

I'm pretty determined to go ahead and get the edge juice w/attitude when I get back home, the only other mod I would end up doing is intake. Thanks guys!!

 

Re-load the fuel card. IMOP

 

I have not put one on my 6.7 yet but on my 5.9's I saw 3 mpg or better, depending on how I drove it.
