This work concerns a Volkswagen Golf with a 1.8-litre turbocharged engine and a Bosch ME7.5.1 control unit. The video title refers to Stage 1 calibration and a popcorn-style rev limiter.

Stage 1 software is tailored to the specific engine and ECU. The popcorn setting concerns engine behaviour near the rev limit; it does not, on its own, determine a power increase.

No power figures or test results for a specific car are stated, so a numerical gain cannot be attributed to this work. Assessing the outcome requires the vehicle configuration and a measurement.
