Your stock file is savedWe read and archive your factory file before a single byte is written. You can flash back to stock at any time, free.
Verified writes, safe abortsEvery flash is checksum-verified. If the connection drops mid-write the process aborts safely and can be resumed — it does not leave your ECU half-written.
You talk to the calibrator11+ years of in-house VAG calibration. The person who built your file is the person on the phone — not a reseller passing on someone else’s tune.

    Best Bang For Bang

    Posted by Joe on Jul 26th 2023

    Extremely satisfied! Was going to wait 6 months to review but after a few weeks of daily driving and putting this thing thru the test I finally decided that this is the best tune you can get for this car . Car works flawlessly and performed great with bolt on mods . Already ate 3 buddies and 2 strangers . One of them being a Ford Sho 2016 with the twin turbo 20 roll 30 roll and 40 roll

    The stage 2 ecu came in as it should. Installed tge ecu and car started at first try. Idle is perfect. Power transfer is linear and smooth. Boosting as advertised. This is a good tune.
