Learning experience for me, high flow intake must require tuning again. I just thought it would complement the current tune but of course, i have no idea.
So did u revert back to stock VNT boost control or just plugged in connector.

Should modify one thing at a time so u can identify what is actually going on.

See if u can get hold of a scan tool and erase any fault codes.

MAF voltage measurements would be benificial to identify any variation between intakes.
