If I buy an 05 and want to get a smarty, is there a certain one, or are they all the same? Also, the edge juice/attitude hot for 05 does 180 hp and 440 tq.... is the Smarty going to be any better in this case?

 

The s-06 version is the current one being handed out to customers 03-07. The loaded software won't compare to the hot-unlock of the Edge, but bump up to the TNT or beta softwares and the Smarty will deliver whatever you can support up to 600+ hp/

 

600?????? How so?

 

If I find one on the classifieds, Is the s-06 the only one that works?

 

I'm saying with the right supporting mods the Smarty can support high horspower and stacks really well. Yes, the s-06 is the only on that works as far as i know...

 

S04 covers year models 03-05.Same tunes available for it as the S06.

 

s-0.4 or the s-0.6 will both work. the smarty has more capabilities than your edge w/attitude. you will be happy with the smarty.

 

let me reword it, the s-06 is the only one available now unless you find a used s-04.
