I installed the Edge Platinum and a 4" silverline exhaust 2 weeks ago, when i first put the module on level 5, and stepped on it, a cloud of black smoke would appear. Now after 2 weeks, there is no more. Is there a reason for its disaperance?

I kinda liked the cloud of smoke when i accelerated hard, if its completley gone, is there a way to get it back? with possibly more smoke? haha

 

That black smoke is not a good thing. That is just unburned fuel that is burning off in your exhaust creating higher EGT's. This is caused when the truck is not getting enough air for the fuel to burn completely. Basically just wasting fuel and fuel mileage.
