Smarty Question
I noticed a big difference as well. One thing i learned was that you DO NOT want to stack the Smarty with the Edge if you want to run the Smarty's timing. Bad idea. The Edge runs its own timing so your timing is already accelerated before you load the Smarty on. The odd numbered programs are fuel and timing and the evens are all fuel with the Smarty. I know from expirence what the truck does with with them stacked and both running timing you will double time your truck and in short motor go boom. I stacked them both on timing on my old grey 5.9 and it didnt run healthy so i ran the Smarty on all fuel and the edge did the timing. Great set up in my opinion.
and its going to cost a little to upgrade to it
