After 4-5 Months of driving with an aftermarket ECU tune I decided to go back to the standard tune.
I was getting easily 500-600km out of a tank with the ECU tune, depending on the amount of freeway driving. Prior to the ECU tune I was getting about 50km less on the std VW factory ECU. Now that the original tune (I hope...) has been reloaded by the tuner, I am getting about 350-450km out of a tank with the same driving style. This seems a bit on the low side and I am aware that the temperatures have dropped compared to summer. So I am wondering where I can obtain a standard factory tune to ensure that the mapping in the ECU is exactly as per factory settings.
I still have a cat-back system fitted, which I intend to retain and the car has done 15,000km.

Any forum members, as well as Melbourne VW dealers / service providers on the forum that are able to assist or have experienced a similar issue, please reply or pm.

Thanx in advance.
