For the people out there with a JB4 installed, is the JB4 worth it? I’ve been on a ride on map 1 and the difference wasn’t too obvious. Obviously you can run more than just 91 octane but strictly map 1, is there a night and day difference? My impression was a slight power bump, but nothing to knock your socks off. Maybe I’m wrong.

I have had Jb1 vrtuned box and now jb4


Jb4 on map 2 is a animal imo.... Sooooo much faster

You're asking a painfully subjective question that's going to draw a million different perspectives. For the lions share here, map1 may as well not exist. Map2 or a location specific map6 is the norm.

For the $750 all-in price, it's worth it for the logging alone. The freedom to spend a few hours tweaking a map6 specific to your conditions, makes it an incredible value.

Theres still no real dynos with before/after for the Facelifted C43.

We'll get some dyno numbers soon. It's not easy to trek down to Weistec, it's a good 6-8 hour trip back and forth for me.
