I'm runnin a Smarty Revo TNT with Edge Hot stack.. It works awesome.! I have to be a little carefull with the timing on the Smarty.. With a stock CP3 it sucked.! I could only use one or the other.. Smarty on 6 or 8, and to even turn the Edge on 1 it'd make my egt's skyrocket..! After installing dual CP3's i can run the Smarty on 6 or 8 still, and the Edge on 6 Hot and tow light 2axle trailers with my toys on it and manage the egt's just fine.. My truck is a '03 with 90 hp injectors, plus a few other Mods...
