Default WGDC very high with slight underboost - 05-19-2019, 11:27 PM

Hi,
can you please help me troubleshoot this?
The WGDC touches 90 when it strives to get to target of 18PSI. Still, I stay a little below. The wastegates were adjusted on my turbos but still, it behaves like this. Maybe some play in the actuators..
Is there a way how to troubleshoot this? Is it possible to have a leak, when the turbos are not that bad when driving.. Thanks

Given you have upgraded turbos- Id think 18psi would be a breeze.

Have you performed a boost leak test?

I have to do it..
Before the turbo adjustment, the flap on my front turbo did not close properly so it did not spool very well. Two months ago, my indy adjusted it, but I think he did not do the boost leak test, for some reason he does not like it, even though I have the equipment.
Now it spools much better but after, it struggles. So, OK. We will do the boost leak test and also check the vacuum lines.
