Hey guys got an offer on my truck today and if all goes well will be selling come saturday. Ive got it for sale over on df but anyways heres my question, I really just want to go back to a stock truck and leave it alone and really want a 2011 to current denali 2500hd. So my question is what do i have to worry about with the lmls besides the emissions stuff?? Any input would be appriciated thanks.
