Had the Hartge tune completed yesterday. Initial feedback: Huge difference in power output in sport and sport plus mode through the lower to mid range. However in comfort zone I am pleased to report I can feel a marginal change in acceleration. Exactly what I expected.

As this tune was only completed yesterday, I need some time over the next few weeks to really analyse the acceleration and power. Will have the dyno completed over the next few weeks.

My next dilemma is where do I have the next service done? At the dealer or the performance centre that did the tune? Feedback please?
