Some more updates for the Stage2
BMS was out doing some VBOX testing with the 328i. 0-60 in 4.6s and a best 1/4 mile time of 13.0@109. Knocking on 12s door.
The car is still completely stock other than the JB4 and E50 fuel. This was using map 7 which peaks at 23psi.
They are planning to do some pump gas dyno testing later this week.
