The Duramax 4.0 Plus, for 6.6L 2007.5-2010 trucks. The Duramax 4.0 Plus is designed to be a fully reversible DPF maintenance tool for trucks equipped with DPF filters. We know that many people use their trucks for pulling and hard work so the 70 more Horse Power comes in handy. We do not modify the shift point in anyway so there is no need to worry about transmission failure down the road due to improper tuning. We understand that these trucks are a lively hood for many, so we have taken extra care to ensure that this well rounded tune will be a good fit for any driving style. This is the electronics only for use with a racing exhaust kit or maintenance pipe.
