I have the Edge Evo CS programmer for my 04 lb7. ive tried out all the power levels and for some reason even when the power level is on extreme im not seeing any black smoke. the truck pulls good and runs good on extreme but i was expecting to see black smoke. my intentions arent for it to pour out smoke but it makes me wonder if it may be running lean? its stock injectors balance rates seem good when i test them. any thoughts anyone?
