Strange one. Definitely try changing the plugs to NGK BKUR 7ETs to see if this solves the problem.
In the past I have been in a Coupe that has run higher boost with the old plugs (6ETs), and especially in the morning or when cold (weather) the car would for a split second "stall" under acceleration, which was quite concerning as it felt almost catastrophic. Initially we turned the boost down and this "cured" the problem, but as soon as the boost was turned back up the sudden "stalling" on acceleration re-appeared. Next step was to change the plugs to a colder type "7ET", this immediately cured the problem, we put boost back upto 1.3/1.4 bar with no noticeable problems.

20 years later the theory still applies, more boost colder plugs, better get checking……
