Tuning guide for VAG platform

We have done extensive research and developed on the VAG EA113 & EA888 engines over the past 14 years. Our inhouse development has allowed us to produce some of the most advanced market leading calibration across all software variants commonly found on this platform out producing the competition. We have gone from the EA113 TFSI engine in both K03 & K04 variants used up until 2012, into the Gen1 EA888 right through to the current EA888.4.
