I participated in a race event last weekend and did a lot of good races.
One of the car I raced against was this BMW M5 e60 which is tuned to about 560 hp with a lot of mods.
My mods are: Vishnu V3.1, UR catted DP´s, Milltek catless exhaust, Race Cooling IC and DCI. And of course pump gas in the tank.
The race goes from 30 mph to 160 mph:

I´m really happy that I was able to hold him behind me all the way up to 160 mph!
My car ran great the hole day with no limps or problems at all!
