Had my mot done today on my frst, and the emissions test came back as
CO: 5.47% and HC: 2830 PPM (failed). the mot tested fiddle around with the car and got them down to the legal limits which are CO: <3.50% and HC<1200 PPM . I had my car set up on the rolling road a year ago to the spec i have which is-

stage 2 chip (motorsport developments)
cossie fuel pump
beige injectors
t3 turbo
piper 285t2 cam
pace cooler
and was r/r at 200bhp@ 14psi

my question is now the mot tester has fiddled with the emissions of the engine will it mess with the fuel of my car? and should i turn down the boost abit in case theres not enough fuel at full load? also does n e one know the CO AND HC figures i should be looking at for my engine spec? cheers

 

hiya pall i would turn it back to were it was cos it will have been set up like that or go back to place that did the work on the engine and let them chek it over
