has anyone bought and tested out the JB4 tune on the GT trim I've seen some good results for the 1.6t but was wondering if anyone had any experience with it.

I know they did a GV80 2.5t and saw good results on E20.
From what I see on the forums, people are testing it with great results. Only thing is, something about the connectors. Not a perfect fit on the beta version. They're trying to source a supplier for the proper one.

Let us know when JB4 will be available. JB4 + cold air intake, k5 will be as fait as a Stinge.
It's already available.
