1.21.19 – On-Track Testing BMW F80/F10 (M3/M4) Stage 1 v1/2 Tune Files —

A quick blurb:

Some pics from today at Thunderhill. Great event! Ren Chang did a great job managing all us monkeys 🙂. I got nearly 5hrs of track time between driving the m2c and 458. Lots of fuel and brake pads were consumed.

Check back for a writeup about our test day soon!
