possible boost leak

[Green82]

question guys my car seems to have lost top end power as it dont get up to speed as fast as it used to.
when giving it throttle i can hear a whining sound (never really noticed it before but could have always been there lol ) you guys think it can be a boost leak or something worse? but other than that car seems to drive fine good low end torque just dont seems to have as much up top

It might simply be a matter of being bogged down by a bit more heat soak with the warmer weather. These cars are noticeably quicker in cooler weather.

I experienced this issue a week prior to my check engine light coming on. Check cylinder #4 coil and plug.

Do your very best to check ALL the hose clamps after the turbo, all the way to the to the intake manifold.
All mine were barely tight.

Make sure there isn't a rip in the throttle body coupler. very common issue
