VW Golf 6 GTI 2.0 TSI K04

The race fuel remap for our K04 setup produces significantly more power than ordinary K04 remaps.
The VW Golf 6 GTI 2.0 TSI K04 104RON remap is  meant to be used for drag racing with excellent results over larger turbo opponents.

How the race fuel upgrade works

By using higher octane fuel, it is possible to produce more power on the same turbo, improving times greatly. The extra power comes from the efficiency of the fuel type, not the turbo itself. This allows for the engine to make better thermodynamic use of it, making combustion more effective.
EA888 engines can produce an enormous amount of torque with the right fuels. MaxTuning demonstrates how it works!

In terms of hardware, nothing more is required over a good K04 setup. The engine needs to be in perfect condition and the spark plugs brand new as race fuel fouls them quickly.

      Having your car checked and logged on dyno is a good start, whether you choose to stay with your current tuner or ask for help elsewhere.
