When my rpm goes past 3 weird weak sound from the turbo or intake. I do not gain anymore power after 3krpm. Seems like my car skips a "heart beat". Just installed a new high performance clutch 2 weeks ago. I already have 200miles+ before reving the engine( I was advised to have 200+miles before reving).

Advice, suggestions would definitely help. Thanks

 

I would start by doing a boost leak test.
