I know that the SCT is the best and safest programmer for 05+ PowerStroke, but a friend of mine has a new duramax and I told him to wait on getting a programmer till i check with ya'll. So which one is the best, I want to tell him the safest (that will not tear up his tranny or motor) and gives him a little more mileage since the new emissions kills these new motors MPG.

You need to tell your buddy to join "the diesel place" so he can check it out himself. It's a GM diesel forum.
