GearboxZ knows that many people use their trucks for pulling and hard work so the 70 more Horse Power comes in handy. GearboxZ does not modify the shift point in anyway so there is no need to worry about transmission failure down the road due to improper tuning. GearboxZ understands 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.
