Remains of a cat in link pipe. A good blockage. No flow = no boosts!

Check for over-fuelling..... that's what can make them break up as they overheat (read: glow cherry red).

Yup ^^

No boost

The boost is back with a bit more bhp due to no guts in the replacement cats thanks lads for your input

I believe I was the closest to the diagnosis
this is what i said in your former thread on post 28

"maybe a blocked catalyst may also be the cause but that does not explain the large vacuum "

I am pleased that you have solved the problem!

Ahem, 6 posts before yours :

I am going to say an air filter that has collapsed, or a blocked/collapsed cat (maybe).
