Under the hood, the GTI has received a significant boost in performance. The Unitronic Stage 2 ECU + TCU tune has unlocked the full potential of the turbocharged engine, delivering exhilarating power and torque delivery. Complementing this tune, the CTS catted downpipe, APR non-resonated catback, and Integrated Engineering Cold Air Intake have been added. These upgrades optimize exhaust flow, improve air intake, and provide an aggressive exhaust note, all contributing to a thrilling driving experience.
