You did not really answer my concerns as asked..   Re-read what I posted.

Lagging

Tony , thank you for responding motor does not smoke heavy black when getting on plain from what I can see from flybridge .looked at Tony’s tips on aneroid and seen what you have posted . Couple questions, is there a starting point on him many turns you move in that direction, if moved to far what am I looking for to know that I did go to far etc… do you adjust when motor is running ? Thank you for your time .

Are you sure there is No Dark smoke during the  lag time???   Engine reach rated + RPM with the boat all loaded up??

If so, sounds like a “Lazy Aneroid” symptom

Let’s see some turbo/exhaust setup pics and general engine install pics.

Has the exhaust ever been pulled from the turbo for a turbo inspection?

What’s the history of your ownership of the vessel and the onset of this issue?
