I just happened to catch this today. I was looking at my datalogs from
different runs, I noticed that boost assist doesnt start until 2500RPM. Why
does it start so late? Is there anyway to start it at 2000RPM instead? I
didn't see WG% going up to 98% until 2500RPM.

What was your MAP? I believe there is a MAP cut over as well.

I can see WG% at 98% lower (2200 RPM for example) however only
once MAP was over 115. This is something I can log in 4th or 5th,
but not earlier gears typically as RPMS climb too fast.

Your wastegate probably doesn't start to crack open below 2500rpm

Most wastegates start to crack open around 120-125 kPa, so the boost assist=
starts at 115 kPa (if rpm is anywhere below the wgrpm setting) to prevent =
it.
