Performance Comparison VW CBEA-CJAA 2.0L


VW CBEA-CJAA 2.0L Tune Details




Production HOT Tune
142 hp @ 4000 rpm 162 hp @ 3500 rpm (> 160hp from 3300 - 4000 rpm)
239 lb-ft @ 2000 - 2500 rpm 316 lb-ft @ 2350rpm




As presented above, the GDE tune achieves huge gains along the torque curve for improving the performance gains. GDE also achieves engine power above 160hp from 3300 - 4000 rpm which improves the pulling power when accelerating for a smooth, linear feeling. Declared gains are 70 lb-ft (at 2350rpm), 20 hp @ 4000rpm, and 24hp @ 3500rpm. These performance improvements translate to approx. 1-1.2sec faster in a 0-60mph acceleration (from standing start).

Real-world Consumption Improvements
One of the main goals of the GDE tuning is to achieve a cleaner combustion output that results in keeping the engine cleaner internally and gaining fuel economy. These changes translate into a direct fuel cost savings to the customer which not only saves money while making the vehicle more fun to drive, but also gives a payback to the cost of the tuning. Characterized over a repeated drive cycle, the GDE tune delivers consistent and proven gains in fuel economy. Depending on your drive cycle profile, improvements are in the range of 4-7 miles/gallon.


A fleet of beta testers ran for 3-4 months before public release of the tune to validate the above claims and over 20000+ miles all data is confirmed.

Benefits and Features of the GDE tunes for the VW 2.0L CBEA-CJAA engines

  • GDE Combustion Concepts
    • Optimized fuel economy (4-7mpg* improvement) while driving
    • Reduced engine soot (in exhaust, in intake manifold, and in oil)
    • Engine longevity increased due to cleaner combustion
  • Improved idle management
    • Warm engine idle speed lowered to 750rpm for fuel consumption improvement (40%)
    • Cold engine idle speed increased for faster vacuum build-up for turbo response
    • Modified idle control during coasting to eliminate unnecessary fuel burn
    • More responsive idle torque controller to make easier launching the vehicle on the low idle governor instead of needing to apply accelerator
  • Enhanced DPF management
    • Updated soot models and regeneration triggers based on GDE Combustion Concepts
      • Longer intervals between regenerations, 700-800mi or more in certain conditions compared to 100-300mi with stock tuning
  • Better transient engine performance
    • Faster time-to-torque giving elevated customer confidence in the driving experience
    • Required accelerator pedal effort to hold constant speeds is reduced
    • Engine performance is improved over stock from sea level to 12000ft elevation
  • Activated exhaust temperature limitation strategies for engine hardware protection
  • Modified high pressure fuel pump control strategies
    • Lower pump hardware noise (due to filling volume in pumping chamber)
    • Decreased fuel heating when not needed
  • Two-footed driving permissible in all conditions (no torque cut)

  • * 4-7 mpg fuel economy improvement is an estimate based on engineering tests and data collected: your personal gain might be higher or lower depending on your usage and driving habits.
