Buick Rainier 4.2 V8 279hp Stage1 Tuning File
We ensure that the 279 hp / 373 nm torque engine power produced by your Buick Rainier 2004 - 2007 model vehicle with the standard option software reaches 295 hp / 395 nm torque after the application of the customized Buick Rainier 2004 - 2007 vehicle software (Buick Rainier 2004 - 2007 Chip Tuning). After the +16 hp / +22 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 Buick Rainier 2004 - 2007 vehicle takes an average of 1-2 hours, please contact us for more information.
