That is great to hear :-) It just shows how close you were with the tune. I actually really like it. I tried a tune from Praiano, who is THE GOD tuner for all things GT and I actually prefer yours as it handles the higher HP better.
There will be a little bit more tweaking with this but I am very happy with it at this track.
BTW picking up on an earlier comment of yours, yes, it is fun pulling out from behind a Veyron in a Beetle and just give him the finger as you power pass :-))
BTW the Beetle has appeared back in the UCD so I bought 4 more to try some variations since I now have a lot of Porsche motors laying around ;-)
