I had OneClick on my Anni for 6 months(thereabouts) and have no complaints as to it's operation or benefits. AmD reckon they would get at least 180BHP from a 150 and it's possible to stretch to 195BHP (given the right conditions) Only problems I encountered were it found a leak in my turbo>intercooler pipe (replaced under VW warranty) and a mildly slipping clutch(solved with this forum)..
You shouldn't regret it although I am aware of Ianhg's quandry..
I aim this at nobody on this forum but some folk are quick to remember the bad points and forget the good...
I had my PD130 One Clicked in March this year - Car was only just run in, and have done 20K since. For me, its been flipping marvelous. Still returns about 48-49mpg and it has some serious shove. More enjoyable and easier to drive quickly than my S3. Revs easily to 4.5K with no brick wall limiter. If I bought another PD I'd get it done again. But as with all things there is an element of risk you need to personally weigh up.
Have you swapped between the stock and modified program very often?
Not needed to. The car is fine in the performance mode, the dealer has no qualms servicing the car. The only scenario I can think of for reprogramming is when I come to sell it and the future owner wants the standard map.
