thats my setup, when i shift out of 1 into 2 and hit the gas it smokes pretty bad and bout the same from 2 to 3. i dont mind it infact i like it im just wonderin if it could lead to probelms, could it be the injectors. P.S. i know its normal to smoke a little when the truck is bein lugged but u can lug the fire out of our powerstroke and it wont smoke a bit

Completely normal, inbetween shifts, engine load drops to (-) and boost drops as well, hitting the gas in the next gear gets your fuel back up and you will get black smoke until your turbo catches up again. Powerstroke is a different animal altogher, don't get caught up trying to draw comparison's in the two. In a PS, the ECM will only deliver fuel quanti**** that match boost levels so you never get black smoke, the computer just limits fuel to match the amount of boost you have. 6.5 ECMs have no such provision and you get full fuel, the turbo just has to catch up to eliminate the smoke.
