The 991 GT3 is the first GT3 to not come in a manual but if you have driven a PDK, you know how awesome the shifting performance is. So how will this ECU help your 991 GT3 out? Changing the cars fueling, timing, torque limiters, O2 limits, VMax will make the 8250rpm track car rev faster, improve exit speed, gain mid range and top end power, and improve the overall driveability.
