If I'm not mistaken, as various tuners at the moment are unable to reprogram the Siemens EMS used in the new TSI range; these tuning boxes, effectively piggybacks, are being used to enhance the performance of the engine.
DNA Tuning provide a more elegant solution which is to thoroughly and properly reprogram the EMS. This reduces possibility of error codes, as piggybacks often conflict with modern EMS as it needs to properly fool the EMS into thinking all parameters are within standard spec; this means our method is more robust, and allows more refined tuning to allow better/smoother engine operation as well as optimising power levels at a given level of boost etc.
Also, being a foreign product, it may or may not work 100% with the cars we get here.
