What is a Pressure only box????
you are adding more fuel so you are going to get a lot more smoke then you had with just the banks... . i recently stacked a smarty with my PDA and talk about smoke haha but i love it... i used to think it was fast on the SL setting but banks on 4 and smarty on 9 look out it really moves out.
I'm seriously ignorant about stacking. If I understand correctly, in this situation your Smarty is on 9 all the time, and you have the adjustability of going from 1-SL on the Banks. OR do you have the ability of tuning one setting of the Banks tuner with the Smarty?
