Can't answer this, but keep in mind that with the tune the car is making more power at launch and I am still on summer tires doing this in 30 degree temps. Let's see what the car can do in a few weeks when roads are a bit warmer.

That is also 0.4 (not 0.04) to go from 10MPH to 20MPH
How was the install of the JB4?
Any issues ?
No issue, but your first time it'll probably take an hour. There was one connection is misleading based on the pictures in the provided instructions...it requires you to remove the front driver side wheel to access the connection.

I bet i could do it in 30 min now, now that I know where all the connections are.
I really appreciate the reply and information! I will keep an eye out for your times on the leader board. I was happy to see another x3m on the list.
