WG% does not indicate lag. It simply means how much exhaust flow is needed to quickly build boost to target or stay on target. When it shows 100%, you're off boost that's all.

For example, a laggy big turbo car, floor it. WG instantly open to 100% and stay there for like 5-6 sec, before anything happen.

The channels you really need to look at, are 1) pedal input %, 2) torque request, 3) load target and 4) MAP.

Pedal input is driver's intention.
Torque request is how ECU react to your input.
Load target is the calculated load that's actually going on, not the target of load literally.
MAP is the actual boost the cylinders are seeing.

If you monitor above channels closely, I believe you're smart enough to figure out where the lag comes from...
