It looks like your boost spikes and WGDC drops to the 40-50 range waaaay earlier in the rev range than mine. Unless your log started at 3k rpm, my graph is pretty far off.

That log started at 2600 RPM, you're fine.

It could be ok depending on the gear. But you are stabbing it at 1600 and boost isnt building until >4000... this is way too slow, but i usually dont wot until 3k at least so difficult to compare. If in 2nd you're fine, but 3rd and especially 4th seems to be an issue. Stab it in 3rd at 3k, then youll have a bunch of logs from others to compare.

Just for a little closure. I had my turbos replaced under the wastegate warranty, and this issue is now gone.

Car boosts like a champ again.
