A friend of mine had his JCW blasted with walnut shell 2 mths ago and the power, responsiveness as well as FC back to like new car. Most DI engines suffer from poor performances due to carbon build up on the valve even with PCV bypass or with oil catch can. It is somehow or rather become a schedule maintenance for them every 15-20k miles. He is located in US and I am looking for these type of services as well here...
