Volkswagen's (GLI) and APR tuning is a great combination! Here at GMP Performance we love increasing horsepower and making our customers happy with the difference in performance of their vehicle. This APR Stage III+ Kit includes a Honeywell/Garrett Ballistic series ball-bearing turbocharger, cast inconel exhaust manifold, larger mass air flow housing, cast silicone intake hoses, high flow fuel injectors, and an upgraded fuel pump. Together with the APR ECU calibration these parts add up to almost double the stock horsepower!
