Boost leaks often produce bucking.

Tested for vacuum leaks

Bought compressor (he-he)
Made 3' PVC plug tester.

Pressurised - and air rushed thru oil cap.

read archives - needed to plug hose from turbo intake to valve cover.

Plugged hose.

Pressurised again.

No visible leaks

Closer to 20psi hose to turbo became twice bigger and was ready to explode.

shutted down air. look for leaks.

None.

What is the next step?
