Bought the car new in June,I've been waiting for the Cobb firmware patch ,with stage II parts installed car finally hit rollers at Dirty Racing Products in Green cove Springs ,Florida and personally tuned by Mike Botti of EFi logics.
Parts list includes:
ETS turboback "quiet" exhaust
P&L upper and lower tgv deletes
Car is totally different,can daily and cruise on highway without any boost but hammer down and zero knock and smooth all the way to redline,sad that you have to spend so much money to get a car to run like it should from the factory,but I'm happy and still get great fuel mileage .Under good is cleaned up a lot,you can see and service about everything now .
super smooth and zero knock
