Thanks Rhyso
No probs.
When does the issue occur? Part throttle? Full throttle??
To get accurate boost logs you need to floor it in 3rd / 4th gear from approx 2500rpm to the red line.
I'd suggest using a private runway of course
Also try Block 23 / 25 - that should give you engine load request
Not up to speed on the MK6's but certainly on the MK4 that's a useful block to measure
