my mot man is quite good on emissions

but i want it to be correct

the ecu and fpr have never been touched since it left the factory

well until i got hold of it and put a stage 3 chip in to run greens


i know the fpr is low and should be increase but need to know if its vac on or off

and shouldnt the co b around the 2.5-3.5 mark? as last time i took a cossie to the mot station it was running 1.2
