Is it normal to not see smoke or very little when running the Edge programmer on Level 5? it is making me nervous. but my exhaust tip and my fender are very black with soot and i either run the truck in Level 1 (fuel mileage) or stock.

Thanks

 

My buddy has one of the new ones and does what yours does my other buddy has one of the older ones and it will lay a cloud out

 

get some schaffers red lable and change your fuel filter and air filter

Thanks for the tip. Going to change the fuel filter and there is a pre-filter before the Foss Pump. I will also change the air filter but, the filter gauge indicator has barley moved. This K & N Filter is maybe a yr old.

Thanks again, I will update when all has been changed.
