Your FF needs to learn up. Starting logs at 5K rpms does not help with that.

Set FF to 70 and do a few proper logs.

Here are the latest log files
Whichever map I choose, the boost does not change
It spikes to 24-25 psi during gear changes, and then drops to 21-22 psi and holds it there until redline.
This is the same situation with all the maps, 1 thru 7

You can consider this as an R&D donor. I have many people wanting to buy this car and asking me my opinion about it. Although the car has a lot potential, these problems looking insoluble makes them change their minds. I have been one of the biggest supporter of the Burger family for the last 10 years and I hope to get a solution to this as soon as possible.

I am not sure if it makes a difference or the cause of the problem but this car is a EU-Spec model, therefore it has different cats and limiters
