Matt brought us his 320i xdrive in for a stage 2 tune and downpipe installation.
We first did some 0-100 testing to see where the car was at stock.
We managed to get 7.73 seconds with 2 passengers on 91 octane.
After installing the VRSF catless downpipe and our ECU tuning software to stage 2 we shaved off 2.57 seconds from the stock time. 91 Octane gas was used in both runs and 2 passengers.
