GMC Sierra 6.6 Duramax 365hp Stage1 Tuning File
We ensure that the 365 hp / 894 nm torque engine power produced by your GMC Sierra 1999 - 2007 model vehicle with the standard option software reaches 395 hp / 945 nm torque after the application of the customized GMC Sierra 1999 - 2007 vehicle software (GMC Sierra 1999 - 2007 Chip Tuning). After the +30 hp / +51 nm torque power increase, your vehicle's exhaust emission values do not change and do not smoke.
We enable you to use it safely by revealing the power that the factory has restricted due to parameters such as taxation system, sales policy and fuel quality, with licensed software. As a result of this process, there is no harm as the limits set by the factory are not exceeded.
The chip tuning software process to be applied to the engine of your GMC Sierra 1999 - 2007 vehicle takes an average of 1-2 hours, please contact us for more information.
