Poor acceleration/boost leak?

So, if you've seen my previous post, i've recently dealt with a failed fuel injectors/o2 sensors. Now today, all the injectors and o2 sensors been replaced. I decide to take car out for test run everything felt fine, until I tried to go into boost. Car has no acceleration, especially up top. I checked the charge pipe couplers (aluminum pipes) and they seemed okay ( will double check in the morning.) The turbo is also making a faint "weeee" sound, similar to boost leak, but not sure where to look.


I have aftermarket intakes and i used to have the lower half of the intake box underneath both intakes, now i just have it under one ( will replace it tomorrow.) Any tips on where i should begin? car stalled 3x after coming off freeway at the light. Ill post a few logs, hopefully they'll be of use. Thanks in advance.

First check your little air tube that connects the J and the long intake tube on the driver side.

Next check the o-ring and the short plastic stack/riser that comes up to the passenger side intake tube. Put a little silicone grease or PJ to assure a good seal.

You can do the same grease up at the o-rings at the bottom of your CPs.

That popped off on mine after more than 6 months with a new top mount, surprised me after that long so I didn't look there at first.

The big coupler where it meets the charge cooler. Going to put a vband clamp there.

Just use the factory Norma clamps. They're top quality, have a spring, don't pinch, and fit the inlet groove well. Crank till they pull into the rubber a tiny bit then stop.
