Glad it worked out for you-----When the LMM's 1st came out I had the 1st 4 tunes come back with white smoke--no power--sputtering--I tried like heck to figure it out and at the time beacuse they were so new--no one really knew much about how to tune them properly and work around the DPF filter-
The biggest problem was not having a LMM of my own to work with--So I finally called one of the LMM guys that had the issue and offered him $100 to borrow his truck for a day and use it as a ginney (?) pig--and promised to return it back to stock when done---I strarted by changing one table at a time -starting with the most important stuff 1st--and worked my way down--When I got to the EGR parameters it started to smoke/sputter---Yea !!! so from then on i just leave them be on the LMM's--- ( my favorite Duramax is the LBZ ) responds well to tuning--no problems--no codes--shifts well--learns fast--some guys around here in 2007-8 were ordering NEW trucks and paying extra for the LBZ rather than the LMM---
