And what's looks without brains? More processing power, memory, and storage to flash faster while saving all of your maps and logs. This is your new Accessport.

EQT ECU Tuning Results/Power Estimates

This is a question asked all too frequently, and while we’d love to give you a specific number, there are many variables involved that can affect dyno results. Even taking the car’s modifications out of the equation, there are other variables such as weather, elevation, fuel quality, dyno type, dyno fan setup, etc. that come into play. With that being said, these are ranges that most vehicles will see, given standard modifications and reasonable conditions:

  •  Stage 1 GTI/A3 - 270-310whp
     Stage 1 Golf R/S3 - 300-360whp
  • Stage 2: GTI/A3 - 300-340whp
    Stage 2 Golf R/S3 - 330-390whp

Here are just a couple of examples of our tunes. Please note that these results were acquired on our Dynocom chassis dyno in 2WD mode and close to optimal conditions. Dyno numbers can vary greatly depending on dyno type and conditions.   

Here are graphs of results from our latest Staged Tunes for the Golf R/S3:

*Results may vary. Power as tested using these identical calibrations. Generally speaking, the 91 octane calibration has a richer fuel curve and a less aggressive ignition advance map to help compensate for 91 octane fuel and/or less than ideal atmospheric conditions. The map designed for 93 octane is the most aggressive.
