40-80mm3 fuel and it only makes around 6psi of boost? I would think it would be higher.

My truck does similar stuff... when I go up fairly steep hills around 80km/h and its in 5th with the TC locked it smokes. My solution has always been get on the throttle more so that it builds boost/speeds up or I just put it into 4th gear for the hill.

I tow heavy loads and I used the trans tuning to keep the converter locked most of the time.When it started smoking with the tunes I decided trying it in non towhaul and it worked out well.

dont know on a LMM but best luck i have had with smoke free tunes on my lb7 is the MAF limmiting table , so it limmits fuel till X amount of air flow is acheaved . but it comes at a cost................. of slower response/power till the air arives but it does work .

I have thought about that. I just don't want to use the MAF limiting table. :(
It sounds like the injection table might be the best way to help control this smoke.

I have been doing this. It is starting to get old and annoying :)

Thought maybe it was a tune in his library. I would say he has the fuel turned up as well. Only tune I had smoke good is script the CP3 tune out of the LBZ onto my stock LMM tune. That smokes good and doesn't take much. Other than that the tunes in the library are pretty good for most non smoke. Most not set with lift pump involved. Good luck there on fine tuning it. You have one nice setup truck.
