The MED9.1 engine ECU software was tuned on this 2007 Volkswagen Golf V GTI with a 2.0 TFSI engine. The work included a Stage 1 calibration and the customer's requested Popcorn sound effect at the rev limiter.

The Popcorn feature is a separate software setting that changes the engine sound at the limiter; it does not, by itself, confirm a particular power increase. The video does not list dyno results, so no post-tuning power or torque figures are given here.
