Question Strange problem when 5 up

Has anyone ever experienced some vibration when flooring it in 2nd and 3rd gear (didn't try 4th and 5th) when there are 4 passengers in your scoob,
It feels as tho' it's coming through the transmission / diff, or like driving over ridges in the tarmac but it seemed to only happen around the time the turbo kicks in and/or on high boost.

I Also noticed that with just me in it a few minutes after that the boost was up around 1psi.?

Any help/info much appreciated.

PS- gearbox and diff oil is due for changing soon so I might try it again and see if it still does it.

Sorted by bending the bracket slightly to the side.
havent had the chance to have a look yet though!!

Exclamation

I supose the exhaust would move more violently with the engine under more strain, and the rubber that the exhaust sits on could be loose enough for it to shake,
or maybee its just the movement of the exhaust on the rubber brackets under the added strain causing the vibration?.

Cheers.
