How do you adjust the N75?

Default d'oh, log 003! I did a little of this today, before adjustment. So is this throttle cut?

doesn't seem like it to me, as angle stays at 100%

Default Nope, you're all good. Looks like the N75 adjustment did the trick. The reason most don't like this

method is that after tinkering with the N75 mroe than a couple times, it start to not react to changes in position anymore. It can also cause a change in the entire boost curve, not just the spike.

Default nope. looks fine. the DBW will ramp up the throttle plate to 100 for you even if you don't roll on

TC is usually after the throttle plate gets to 100.

that was before adjustment. So what was causing the surging if it wasn't throttle cut?

Actually, after taking a closer look, it seems like you did cut throttle but only for a moment ~3200
