It’s the final year of the Mk7 VW generation and COBB is here to send it off on a high note and we were able to kill two birds with one stone. As of today, COBB Tuning Accessport and stage package support for the 2021 USDM Volkswagen GTI and GLI is live!

Engine Tuning

The 2.0L turbocharged engine found in the GTI and GLI already serves to make the cars behave like a wolf in sheep’s clothing in stock form but with the right set of simple and effective aftermarket tuning accessories. They become more like a rabid saber tooth tiger in sheep’s clothing. There may not be a better bang for your buck tuning platform on the market and the Accessport makes unleashing that potential as easy as possible.

Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Follow our staged upgrade path with pre-loaded Off The Shelf (OTS) maps or use custom mapping for any modification level.

Stage Packages

Tuning the ECU with the Accessport is fun…but making even more power with high-quality bolt-on parts while tuning with the Accessport is even more fun! Our engineers rigorously test hard parts to find the perfect balance of VW performance parts.  Specific GTI parts require specific ECU calibrations and vice-versa, so to make it simple and easy, we offer several stage packages to make sure you get exactly what you need and save a few dollars with a bundle discount in the process.
Note: Some parts and packages may not be available for purchase in California. Please see our COBB Green Speed documentation for more details.

Custom COBB Features

Not only does the Accessport work to greatly improve power and response, it also comes with a set of custom features and tuning options to add even more value to the experience.

Custom Tuning

A major advantage in purchasing an Accessport is that it is pre-loaded with several Off-The-Shelf tunes for very specific bolt on modifications. But we also have a great network of highly experienced and approved COBB Protuners that allow you to have a one of a kind custom tune created just for your car using our Accesstuner Pro software.

  1. Hi, I live in California. I want to start to build out my 2021 GTI some and was looking at going towards Stage 1+ with the Redline Intake (part 7A1100). The Stage 1+ package with the other intake (VLK002011P) has a CARB EO but the 1+ package with the redline (VLK002011P-RED) does not. Is that a mistake that it is listed as not for sale or use in California by chance? I can buy the parts that make up the package, but not the package.

    Thanks for your time!

    • Hi Daniel,

      The submissions are pending for the packages. The package itself is not yet CARB legal but the parts individually with the map you’d run are. It’s a bit confusing but for it’s own CAR EO, the package requires its own submission which is still pending.


  2. Hi where do we stand on the DSG tune for 2021? Is there at least a rough estimate on when to expect? Also does the DSG tune impact transmission life negatively at all?

    • Hello,

      It is still in the works! There is not a firm ETA as of now but it won’t be much longer. It will not negatively impact the transmission.
