Sorry if this has been covered before, I've tried a search but can't seem to find a search term that filters out irrelevant stuff!

I have a Blitz cast Iron de-cat system which I would like to fit to my Mk 2 rev 1 turbo.

I have a mongoose ss exhaust fitted.

As far as I can tell, I have lambda sensors after the cat too.

what if anything do I need, to fit the blitz.

I am asuming that the ecu will need to be fooled into thinking the cat is still there, otherwise won't the ems play a merry dance?
Advice very welcome
