a) If you can hit the manufacturer claimed 3.6-3.8 second 0-60 times
b) If the Jb4 log from such event shows the actual boost in each gear, the throttle plate position and the wastegate duty.

Massive thanks for anyone that has this data they can share!
I have a JB4 that I can take logs. But I have ******* *********. So the numbers would be skewed.
