Happy Sunday everyone,
I'm still waiting to hear back from my tuner, however I'm having an issue .
Didn't seem to have issues at the local track .. ran an 11.8 @ 122mph .. I know I know not fast. But I was on street tires, rwd, no boosting launches or anything dramatic, tools in the trunk and full interior so I was happy as this was a personal best for this car.

My tuner first observed these strange WGDC spikes from these logs

Then I replaced the boost solenoids and this is the log. No spikes but flatlines.

Tuner thinks I could have an issue with the wastegate either not functioning correctly or 'sticking' . The characteristics seems to have changed recently. Not sure where to start as I'm not getting any codes. I did have a #6 misfire recently, however I pulled the plug and it was gapped too short, so I opened it to what it was supposed to be .022 Now no misfires however I'm seeing strange throttle and wgdc behavior.
I'm hesitate to revert to the previous revision, but as a teachable / learning moment I'd like to have more eyes on the logs so I can ask intelligent questions when I speak to my tuner.
Hardware
* 17ts [I know I know]
* BMP Full PI with Motiv Reflex
* B58 coils with +2 colder NGK gapped to .022
* Pumps and HPFP are all new.
Awaiting my 'custom' fuel pressure regulator to hopefully stop the porpoising / oscillations of my LPFP.
Thanks in advance for any input.
All the Best,
Oh, and feel free to look at any of the logs I try to keep notes and logs of all the mechanical changes.
