100% WGDC, LOW LOAD, LOW BOOST

[deakgegi]

Hi!

I have a 3" catless exhaust, hpfp internals, fmic.
I installed the ots tune from Versatune for 98 octane high load high flow downpipe.
Unfortunately my WGDC quickly goes up, while my boost pressure drops with load as well.
No knock is detected.

Do I have a boost leak?
Whcih components do I have to check, like bpv and wastegate?

Thanks for the help!

On stock turbo this is about as much as you can get. However I'd expect to see more in the mid range but this depends on what intake you have.
