What is your WG value at? What mods? Octane? Your ignition timing is starting at a very low curve.

Looks normal for an 18 ohm.

Not really experienced reading JB logs, but it looks like preboost and target boost are pretty close showing no boost leak.

It looks like your meth (is meth flow shown by PWM?) is lagging in relation to throttle when you you start to go WOT which is causing some timing pulls at max boost. The graph where you shift looks nice in the next gear since meth is flowing full from the onset of the gear.

I would pull the additive to 40 and relog, I'm willing to bet your timing curve will then start at 10 degrees and work smoothly up to 14.5degrees near redline.

Meth is the teal line that says meth on the graph.

What is PWM then? I was thinking that PWM was actual meth flow and METH was called for flow.

PWM is the duty cycle added by the JB4. When it's maxed out it won't hit boost targets. Regulated by 18ohm or 15ohm resistors.

Looks good! Right on target for JB4. As the additive increases, you might see a gap between target and preboost as the autotune monitors the timing keeping 8-14 degrees. It takes a few pulls with traction control off to see smooth timing lines but they will improve.

PWM= wastegate value.
