Buy a boost gauge. Over boosting is too much turbo outlet pressure into the intake manifold. This is controlled via the waste gate Which is controlled by the computer, which is controlled via 0-5v signal coming from the map sensor which is connected to the intake manifold. So unless you have played with the waste gate pressure hose under the turbo then I would assume you have normal boost levels after your throttle body. Your intercooler piping will be receiving higher pressure then designed for when you here the flutter sound and it is common for the hot air out of the turbo to blow through your hot side piping.

Every car with forced induction has the ability to over boost. But assuming everything in your engine bay is working as it should then no, it will not over boost due to a intake muffler and blow off valve delete. Any change to the cat convertor will surely see your car going into limp mode due to over boosting.

What does "dose" stand for?

Hey guys on the weekend I chucked a camera in front of my boost gauge to watch the boost after I finished driving

I went through 1st to 4th, the boost peaked at 12psi on the gauge, I'll try put the video up later

Only mods I have is an intake box with pod filter and removed the bov, everything else is standard just don't want to cause engine problems

Also with the bov connected the car doesn't feel like it pulls as hard then when it's blocked up?

So here is a video of what's happening

Ps: disregard the beeping 80km fuel range
