Thanks both of you, I will check out those tool.
I did make one more test, with little success.
This time I tried the OTS stg 2 AVCS:
It looks like this:
Vs. OTS/OFH AVCS:
I think this has been enough testing for me. I will revert to the OFH AVCS and just correct the lean bit above 4k with OL and live with the dip and leave it alone. All the pulls with the heavy correction to OL shows the delay no matter which gear. So I suppose the conclusion of this could be: For smaller corrections OL is okay, for bigger ones it can potentially mess things up?
P.s. I might try smoothing the exhaust valve below 3600 as shown previously as a last test.
