Hi
Sorry it took so long to get back
I took it to a MOT test centre for a smoke test. It passed with a prity low emitions
.The car is stock but now with turbo back exhaust, Ionly use 99ron fuel so dont know if this helped.
Fast idle test Co Max 0.20% it ran at 0.11%
Idle test Max 0.30% it ran at 0.06%
So I think its pretty good. Looking to have a re map next so I dont keep having the engine management light on and get some more power.
