you might be getting rail pop. i think you have to change the timing to get ride of that. what did you set it to?
my truck NEVER smoked with the smarty. (might be an issue with my truck) i don't have gauges to know what the RP was. if you change the rail pressure setting all it does it ramp up faster. not higher. torque managment will give you more smoke at low boost. if you have a built trans then play away, else keep it at 1 or 2. the timing is where your going to get the best MPG's runing empty i usually ran the timing on wild. when i would tow i uninstalled the smarty all together. if it was any sort or weight. my small flat bed with the Rhino i didn't but the 5th wheel i would.
can you get video of the POP? search rail pop on CF see what they say. there is also a GREAT thread on the smarty setting over there.
