Wont go above 5psi... Help Please

[Blown02]

I have a 02 gt with a forged 01 cobra motor and hp twin 57s.

When I go WOT, it goes up to 5psi, and stops, sometimes bucks.. As soon as it starts bucking at 5psi it wont go above 5psi and I just let off and it drives normal. Drives perfect under normal driving.

The springs in the wastegates are around 8psi but sometimes I see 10psi in different weather..

I checked all the vacuum lines and they are all connected.. Each bov has a line running to the top.. they are both connected.. Each wastegate has 2 lines.. they are all connected..

Any ideas?

Thanks!

It stays at that rpm or drops.. I just drove it.. sometimes it would get to 5lbs, sometimes not even 5lbs.. then it would sputter and fall on its face..

Just looked underneath the hood.. the first clamp was loose.. 2nd clamp was on.. Fixed that.After the traffic dies down, ill go test drive it and see if it fixed the problem..

Sounds like you might have found it, check every clamp on both sides, good luck, hope that was it.

Thanks for all the help!
