Benm, the first dyno shows exactly that, a 98 ron tune with 100 ron fuel, and the increase is the re-tune with no change in fuel. I was expecting a 20Kw increase was at the top end, but only got 10kw where everyone looks, the final top line figure. But the car did get 20kw's+ in some places, mainly in the street and track areas, as Im very rarely at 7800rpm at the track. Another point is the tune is safer then before, more fuel, less boost, less knock and more KW's, the perfect outcome.
I guess the difference was, I did not walk in and ask for as many KW's as possible, I asked for a supper safe track tune that will do 40,000km a year as well as a dozen track days per year, and I need the car to last another 2 years! I would suggest this is not a normal request for a GTR tune, hence why I did not end up with huge numbers.
I guess at the end of the day Im happy with the car and power figures, and as long as Im happy its all good!
