Whilst having a look at a well known internet auction site I came across what was described as aTMIC tilt kit. The blurb stated that the plate nearest the bulkhead was raised creating an angled surface for the air to travel across this made it more efficient !!!!!!! Anyone experienced these, 2 bushes and 2 longer bolts thats it.

 

yes i purchased a kit from carl davey from here. once installed the car definitely pulled with a slight increase in boost on the avc-r.

 

Thanks will look into it a bit more
