The tuning Stage1 for the top of the 991 range has been released.
The 3.8 liters is well known as one of the most impressive engine on the market place, but in spite of its stock quality the performance can still be increased with a proper software tuning.
The stock car is capable of 560hp and 700Nm of torque and we can confirm that after the dyno test of the stock car. The Turbo S in the firsts test is even more powerful with over 570hp (100RON fuel).
The Stage1 tuned car now reaches 611hp and an impressive 872Nm of torque (100RON fuel).
The “normal” mk1 Turbo version can get the same upgrade, because the only difference between the two versions is the software calibration by Porsche.
The first thing you’ll notice driving the tuned car is the torque increase at the lower rpms, that makes the car extremely fast in all gears.
With proper traction condition the 991 Turbo S can hit 100 km/h in 2.6 seconds.
For all the 991 range is already available the new tool BIESSE Flasher, the device which makes you able to switch the original and modified software calibration by your own.
