I'm running your development DP and a resonated system, the system has been completely faultless since day one and offers just the right blend of performance gains and refinement to make the car perfect for both daily use & quiet cruising. It also offers a great sound upon hard acceleration for my Stage 2+ car and exceptional performance for a 2.0T.
We are currently putting some miles on the clock before it enters the workshop for development - a tough job but someone has to do it!
