Just fitted msd 380+ chip and my emmisions readings are 11%+ co 4000+ ppm hc its that bad its smoking and hurts your eyes lol Not saying it's the chip causing it tho.

Any idea's what could be causing it? i tried ringing them earlier for advise but they must have been busy. Going to try a new lambda sensor tommorrow if i can get one. When i unplugged the lambda it went down to 5+% co. Is this normal??

Thanks Danny
