Default B58 JB4 issue? - 04-11-2020, 05:41 PM

I recently installed JB4 last week. Iím running Map 2. Every once and a while Iíll do a pull in second or third gear and the car wonít go anywhere. I hear the turbo start spooling but the car is barely accelerating. Almost as if I was brake boosting it. Itís not all the time but itís happened twice now. I only have about 60 miles with JB4 installed.

You need to post a log. Get a log of the issue so we can see what's going on. Without it, there's little to advise.
