Finally going to bite the bullet and buy one, but trying to decide if the Smarty is worth $150 more. I am not big on modifying and stacking, usually drive like a snail. I just want a little extra performance, lower EGT when towing, and a few more miles out of the tank.
The Smarty JR sounds like it will fit the bill as is, any thoughts?

PS I see that some are listed on ebay for 439 plus 10 shp for JR and 599 plus 10 shp for Smarty.
