New to the site, have had my LMM for a little over a year now. I had a LB7 and a 6.0 F-250 before this one. Have only done "the standard" so far. S&B intake, 5" MBRP (should have done 4"), EGR plate, Air Dog and EFI Live by Idaho Rob. Looking into Leveling and tires right now, maybe more go fast...
