Typically it is difficult to find large horsepower and torque gains by only changing a tune on a naturally aspirated sports car and the GT3 911’s don’t make absurd power like their Turbo brethren. Yet, the results we have been able to efficiently and consistently produce on all of the 991 GT3 variants is a testament to Porsche’s engineering and the enthusiasm and expertise of our own calibration team. There is no better bang for your buck method to modify your GT3 in order to get the absolute most out of such an incredible machine than what you can gain in a matter of minutes with an Accessport and one of our OTS maps. The results below speak for themselves.
Using 100 octane at the race track is certainly the best option for the best results, but do not worry. Every Accessport for a 991 GT3 or GT3 RS includes Stage1 OTS maps for 91, 93, and 100 octane to suit whatever fuel type is available. (95, 98, and 105 RON respectively for international ratings)
Plus you can easily change between each map in a matter of minutes as often as necessary so you are not stuck with only one octane choice.
