Cobb wgdc/PID questions

[jp1]

Hi all, another day another log and question regarding my ongoing issues.

I'm getting boost overshoots after initially hitting the throttle and another overshoot/surge when coming off the throttle. I've been advised to look at the PID tables along with the wgdc base tables for the probable answer. A massive learning curve for me but I'm keen to learn.

One thing I've noticed that on most if not all of my logs the wgdc after pid is lower than that of the wgdc base. Does this indicate a boost overshoot issue as I would have expected the base, well, to be the base.

Apologies if I'm confusing issues here, as mentioned above, very much learning.

Thanks for any help offered.

What are the values in your WGDC airflow adder table? Reduce them first and it should bring your WGDC base below your after pid. I had the same issue on my tune briefly before realizing my adder table was a bit too high.

I'm just running the ots stage 2+ aggressive map, WGDC adder airlow is the same as stock (map 0 on cobb at least)

could this indicate tight/loose waste gates?
