No news about the dyno guy...
Other then that, I've done some test yesterday night... The very cold air here make a huge difference in term of power to my engine! Normally, at the end of the short straight line where I'm playing, I can reach 180 km/h... Yesterday, it was 195 km/h...!
.
I whisper in your ear: cooling! oilcooler, BIG! and revamp the undertray. combined they make a huge difference!
