put the edge on stage 5 to green light with a mustang when i punched it there was a cloud of white smoke not black. just had injectors replaced under warranty about 2000 miles ago. this weekend drove a 400 mile round trip and got 22 mpg which has never happened,not sure if thats related. BTW changed the fuel filter right before i sent it in for injectors. Anyone got some ideas

A really heavy white smoke is an indicator that you have raw fuel in the cylinder. Black smoke is unburnt fuel. Im not saying i know what the problem is but i would start taking the edge off and see if it still does it. If still like that then take it to whoever did your injectors since its still under warranty.
