my dad just bought a 2008 gmc 2500 duramax completley stock i was wanting some advice and whats the best tuning for the money and some weak points in the motors just generally advice on building one thanks
LMM's are very solid trucks, the best GM has built to date. You just have to deal with the emissions equipment then your good to go. As far as modding them, they seem to be holding up decently at or around 700 rwhp on a stock block. The rest of the truck just requires usual maintenance...
