There is also the difference in tuning stillen is most likely using a cobb accessport this time instead of the piggyback they normally use and they have mentioned that they may be divorcing the iat duties from the air mass sensor and relocating them to an individual sensor in the manifold while gtm is going with a blow through setup which means they won't be able to detect pressure in the manifold from the stock 1bar map sensor and the sensors being blow through won't be able to read the extra airflow so there is going to be some serious hacking of the tune on their part to get it to run. both kits are going to have to use recirculation valves as without a pressure sensor the car would run excessively rich on off throttle if vented to atmosphere.
