I was offered a BSR TDI tune by my mechanic today. I have been considering tuning since the warranty has expired. I have over the years been keeping an eye on the different tunes (bluefin, DNA, Oettinger etc.) but haven't been able to find much on this one.

The figures they are quoting on their website are significantly higher than the other ones on the market. I am worried if I was to go with this one, the DSG would need a separate tune as well. If the quoited figures are correct, then I can imagine it might by quite Jerky when around town. Surely, my engine isn't suitable for those sorts of gains.

Anyone have any thoughts or experience with the TDI BSR tunes?
