**You must remember that tune I used is for AUDI RS5 only and it´s set up for fully upgraded car. The 1/4 mile time of boss is 10.588 sec. Fully upgraded AUDI RS5 with tune is at same time as boss so it is very close race. That´s why I used two stage 6 upgrades! Because I didn´t wanted to risk loosing the car and golds :).**\r
