GIAC Tuning

Lüfteknic is a full-line GIAC tuning facility, offering in-house ECU upgrades for most popular Porsche models, as well as select Audi and Volkswagen vehicles. Among the top software tuning companies, we’ve found GIAC to offer the best available upgrades for the Porsche range. Aside from the desired increases in horsepower and torque, GIAC software offers an improved overall driving experience, with better throttle response, improved part throttle performance and sometimes even an increase in fuel efficiency. Most tunes feature raised rev-limits and higher top-speed limiters for the street and track.

Best of all, GIAC tunes to factory correction parameters,  which means that even with the increase in performance, all of your Porsche’s ‘fail-safe’ ECU functions such as knock-control and DTC logging remain intact. This means performance without worry, and GIAC-tuned vehicles with the proper service will typically see no degradation in long term durability and service.
