I chose to go with the Cutler kit. I like the cold air intake setup he has(6 or 7 points of cold air intake) as well as the quality of the kit. Everyone knows Dale does everything top notch. The entire kit is almost completely bolt on. I am not an expert on M turbos but I personally liked what I saw with the CPC kit so I decided to go with that one. Dales kit also uses the Attitude Industries box which I like as well.
