Nope if its for a 06 on up your sol. Theres also better options out there

 

ya ive seen alot of others out there he has i for 175 figured id ask...iam lookin for a decnt price on an edge with attitude or quadzilla

 

What he said. I don't think tuners for HO 04.5-07 5.9's will work on 03-04's. Heck brand new predators for your truck arent but $275. Dirt cheap.

How much are Smarty's? About $700? That would be the best choice, but also probably the most expensive. And I'm not a fan of Edge or Bully Dog for Cummins. Especially not Bully Dog. Had a couple friends that had bad experiences with them.

 

My friend blew a few of his injectors with his edge, he has a smarty jr. now.

 

I have heard alot og good things about smart,noone seems to be too dissapointed with them..iam lookin for a more economical path..dont want too much power jus to tow a camper and car trailer..

 

I think that if you're not too concerned about lots of power, the Smarty Jr. would be good for ya.

40/70/100 hp levels
And sells for about $500 compared to $700 for the Smarty Sr.

 

well iam jus wantin a lil power nuttin crazy..u know how these dodge trannys are..
