That is high you wil struggle to get this below the requirements. take it for a good run change oil and plugs and make sure the mot guy does not have it sat for ten mins before he checks it.
I was getting 5/6 co and thought that was high and I struggled to get it below for a pass.
If you had an aftermarket ECU, Pim and inj can be altered to lower it but not that much, do a search this has been covered many times.

The other option is to find a MOT guy who knows about FD\'s and should be able to help.

As far as  I am aware I thought you were risking your engine running a standard ECU with this sort of modding, I am sure someone will be along to shoot me down.

Hello mate

You are going to blow your engine in  no time with the mods you have running now unless you “stop driving your car” and fit Apexi pfc with a map accommodating your mods.

The map on stock ECU can not be altered to allow more fuelling which is needed with a de-cat…ask any one on this site about this

Apexi PFC can be mapped to acomodate all sort of modifications.…..

I am just giving you a friendly advice if you do not mind, I am sure many members will ditto my tread.
