034Motorsport is proud to offer our Stage 1 Performance Software for the 07K 2.5L 5-Cylinder Engine found in the MKV Volkswagen Jetta & Rabbit!

Through optimization of the factory ECU's fueling and timing maps, the 034Motorsport 07K Stage 1 Tune is able to provide increased horsepower and torque, as well as a much broader powerband. 034Motorsport's engineers have also addressed other shortcomings of the factory calibrations by increasing the rev limit to 7,200 RPM, eliminating the "rev hang" between shifts, increasing the idle speed for a smoother idle, and refining part-throttle mapping for improved drivability.

With the 034Motorsport Stage 1 Tune, you can expect faster acceleration, increased peak horsepower, a large increase in low-end torque, improved throttle response, and a much broader powerband!

This tune was developed in-house by 034Motorsport's expert calibrator, and was thoroughly tested on the street, track, and dyno before release.
