When they custom tuned my car on the dyno it had 213hp before and 292hp after both at 32 degrees Celsius.
So now with the ambient temperature being around 8 degrees celsius- I didn’t think it was strange to calculate to a 309HP.
My fastest recorded 0-100kmh is 5,9sec in 92meters (manual transmission).
I have the performance wheel- with display, so it measures it for me.
