Hi guys, I also have the same form of garret, the I installed in 2011 with an annual mileage of 25/30 thousand km and now problems zero. Even once installed the filter and bmc removed the prekat, I sent a **** the company that I adapted the map of the changes made. The preferred a map because I took it at bargain price(100euro) from a guy that had used on his machine and I have to say that I was satisfied. Certainly the map was better, but at what price?
