I have already considered a cold air intake and upgraded exhaust, but I keep reading mixed opinions online about tuning options and transmission upgrades.

For those with experience using lml duramax performance upgrades, which modifications gave you the best real world results while still keeping the truck dependable for driving and towing duties?
