Thoughts?
Either way, I was looking at the JB4 and JB+ to spice it up even more. I connected with a guy from Burger and he explained that the JB+ wouldn’t even move the needle since the factory tune is so much better this year. He said that I’d have to use map 2 on the JB4 to see any gains.
That being said, if I’d have to be at map 2 to see anything, what kind of overall gains can I expect? I have no plans for any other upgrades at this time.
Thanks in advance for any help!

There is no 2019 M340i is there? 2020 is the first year of it.
