Thanks, that's helpful. I logged another map 1 run today (granted it was first gear into 4th), and I was pretty consistently about 1 psi below dme bt+target. The screenshot from the attached log is all WOT except for a tiny blip.

I do have an EWG harness on order, but I've been told that it is not used until maps 5+. Is that correct, or will it make a difference on maps 1 and 2? What other factors contribute to meeting boost request with no EWG harness?

Boost seems to build slowly at low RPMs compared to other modded turbo cars I've had. I've tried increasing PID from 10 to 20 and FF/WG Adaptation from 50 to 60, but this had no noticeable effect.

WGDC seems to stay around 50-54 during pulls. I've seen logs of a similar car (CT_Drifter...not sure if it has an EWG harness) that showed WGDC around 93. What could be the difference?

Deeply appreciated your prompt responses. I will get my local tuner BMS tuning to data log and send over. Nice day and good health.

Relog once EWG is on, and also log map5 which is an absolute boost target, so we can compare. With EWG on we should see more boost here especially on map5.
