I bought my TDI ECU and DSG tune through GDM. Les walked me through the steps for the remote tune of the DSG. I was impressed with how easy it was having never done a remote tune before. The ECU had to be sent to GDM for the tune but the turn around time was extremely fast. I was very happy with the process. Recently, a friend’s TDI needed a turbo replacement. GDM was the first place I thought of. I called Les and he had the turbo I needed at a great price. The turbo was delivered the very next day and I had the car running later that same day. GDM is a great company with efficient service! Will continue to be a customer. Thanks!
