With each new diesel engine to hit the market the most common question to follow is when tuning will be available. A half ton diesel option from GM has been rumored for years and it has finally been delivered. GM’s announcement of a diesel engine for their half ton trucks has been well received among current half ton owners. As the new 3.0 Duramax rolls out there will be many customers looking to customize these new trucks. While there will be leveling kits, running bars and pap caps available many owners will want performance upgrades as well.
