The external dumps will scream, I mean common, if you're only boosting 6-10psi those dumps are opening up very early. So basically past 1800rpm its as if you didn't have a mufflers at all. ZR should have explained this to you.

Also thats the silliest reason to switching to external gates I've ever heard. You should go back to internal wastegates, I've never had any issue regulating boost on the internal gates that GTM provides, and if you don't like those you can also get dual port internal gates from any garret dealer.

I mean if you wanted just 10psi why didn't you just buy the 10psi wastegates from GTM and ran no boost controller at all?

I suggest you find a more competent shop to work with. Because its sounding like a case of user error.
