Near the end of your log, you're hitting boost of about 15psi on map 0.

Make sure all errors are cleared and then do a proper log on map 0 and 1, lets see how those look.

For proper review and the JB4 to adapt, please do logs in 3rd or 4th gear from 2K rpms to redline at wide open throttle.

As I saw when boost was about 0.2 bar it's was 6999 rmp but can't see it on log, and I think it's not ok if I have 3+ - 7k rmp and boost only 0.2, I'm abit scared about engine now after this heppend few times

Most of the log looks normal but you are having the random issue of no boost on map 0 and 1. Were you clearing the error between each pull? The only thing I can suggest is to check your connections and JB4 board. Make sure there is no moisture and the connections are tight.

Only with map 0 got chech engine, after remove no check,
On map 2 it's feels like car can run much more acceleration ,but not doing it's feels so. Is it possible to run some adaptation for jb4 ?
And any way to do log with out manual shift ?

Some auto log writed I think before it

Looks like a p0049 overboost fault, what mods? You'll likely need JB4 EWG connectors to dial down WGDC.

Bit6 is only if you're currently flashed with an ECU tune.

Either way if you continue to have over boost continue to lower FF. 35, 30, 25, etc as needed.
