Fitted a new msd chip at the weekend for my new spec, got the chip in set the fuel pressure to 3.5 bar with the vacume pipe off, now ive only just got round to setting the co, i popped down to me local garage and on first inspections it was 10% msd advise 2.7-3 %.

Had a liltle playu around but couldnt get it below 8.5, why is this ???

i turned the scre a fair few times and wonder if ive fucked it, ive also herd that it can sometimes need re-setting...

im going to ring msd in the morning for advise but thought id ask on here first as im an impatien fucker
