I tuned BM3 stage 2 91 octane with VRSF catless DPs last week. Been snowy here so limited time to put down power.
I did get a dragy run of 12.12 @ 114.22mph with a wet/slick launch.
1.93 60ft.
0-60 in 3.97, 3.76 with 1 ft roll out.
DA was 8700ft.
Not a bad time. I expected to be in the 11s and close to 115mph in the dry.
My only run stock was 12.31 at 112.08mph. 1.85 60ft.
0-60 in 4.16, 3.93 with 1 ft roll out.
DA was 9300ft.
Feel wise, more power everywhere. Doesn't come on too abruptly down low. My MHD stage 2 F30 340i was pretty abrupt at low RPM with how the boost hit. Made car feel jerky. Top end is way fatter. Just pulls everywhere. I love it!
