Hector from Ohio recently picked up a super clean 2017 CTS-V Sport, and he worked up the perfect fitment with some 20” wheels. We installed an aftermarket intake system replaced the spark plugs and added our intercooler fill and bleed system. Strapped the car to our DynoJet and peaked at 410 whp. As always, air/fuel and boost curves are nearly perfect, and the electronic throttle stays completely open too!
