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

Re: [Mk2] [Turbo] Blitz de-cat
the sensor in the CAT is the temperature sensor, that isn't really used if you have no CAT! Just tie it up and it will be fine, you should have a lambda sensor in the actual exhaust manifold above the turbo, that's the one that talks to the ECU
