I heard that you can stack a smarty with an edge juice with attitude, is that true?

Yes this is true and works great from what I've herd. I think you just have to run the smarty on tunes that only add fuel and let the edge do the timing

Jake is correct. I am running a Smarty and a EJWA CTS. The Smarty usually stays on level 1, unless I am towing.
