Hello

Just installed bov. Cobb stage 1 and twin intake Install good no engine lights.

Goes off when driving at 4000rpm switching gear.

If I switch gears at 5000 or higher there is a delay in sound or some time I dont get sound?

Any have this problem and know how to fix?

make sure the little hoses that go from around the manifold to the flow off valve are all tight in there, mine did the same and it turned out to be an unplugged vacuum line.

ive also heard something about some tunes having a feature that keeps you from loosing boost in between shifts and causes that ? but not sure about that

Should I use a different vaccum source other then stock one

No.

Double check all lines are connected with no tears.
