Log Check - Boost Leak?

[steve30]

I resolved the AFR/O2 sensor issue but the car still spools slow.

Here's a log from 3rd to 4th gear: https://datazap.me/u/steve30/3-4gear?log=0&data=4-5-6-7-8-9-10-11-16-24-25

I see some timing corrections in 4th and the boost bouncing up and down.

Not a tuner or anything, just learning how to look at logs. But one thing I noticed is it looks like your throttle is closing by half suddenly for a second when you reach the boost target in each gear? I wonder if maybe the traction control is doing that if it wasnt fully turned off and is cutting power when you are reaching peak torque at lower speed for that gear? Only other thing I've read so far about throttle closing is if you're overboosting which you aren't going over the target so I wouldn't think that is the case.

I've got no idea what's causing that strange behaviour in the wastegates. Boost seems to climb as they open up.

Spool is slow, what turbo is it?

The tune looks odd though. Almost like there is no PID acting at all, just a wonky base table maybe.
