You will always struggle if you have a full decat, but your co level is way off the chart!!
Could be faulty maf, lambda, wrong spark plug gap. Car is majorly over fuelling, don't think even if you car had both cats you would get the co level low enough.
Check for fault codes on your ecu.
At my last MOT car was 0.45% fully decat or 0.27% with the cat on

thanks 4 reply m8
ive just checked previous crypton gas analysis paper. results on that were 0.30 and car had same mods as now but diff induction kit !
would it make any diff putting a std airbox just 4 the m.o.t test ?
