Nick Murray tests a tuned 2017 Porsche 911 Carrera 4 with a FabSpeed tune, boosting the base 370 hp 3.0-liter turbo to roughly 470 hp. He compares it to a stock Carrera 4S with 420 hp in drag races, finding the tuned C4 is faster than stock but not quite 50 hp ahead—closer to GTS-level performance.
On the road, the tuned C4’s engine shows impressive responsiveness and hits higher boost pressures, making it feel faster than stock, though in drag races it performs closer to a Carrera GTS rather than a full 50 hp advantage.
The video also highlights the car’s optional ACC (active cruise control), which maintains set distances and speeds automatically—even stopping and restarting in traffic—demonstrating a rare but useful tech feature for a sports car. Murray notes that tuning the base 370 hp engine yields the most power, more efficiently than S or GTS variants.
Overall, the tuned Carrera 4 delivers strong performance, engaging engine response, and additional convenience features, making it a compelling alternative for those seeking extra power without upgrading to the S or GTS models.
