I had Abbey fit this system for me and got car back today, it is a fantastic system sooo much better than the oem, totally programmable and the added bonus of launch control. I am off to Somerset tomorrow for a proper play. They also did a 4 wheel alignment which has made the Growler feel totally planted.
Big thanks to Mark, Scott and Charlie for doing a great job as always, i will post up some pics of the control unit on dash over the weekend.
