No probs matey, though you didn't love me anymore!!
You need a gastester/metre to read what it actually is, if a freindly MOT place they will be more than happy to do it for you maybe a few quid ?
Just take off the cover over the ecu and there you will see a screw, this is your CO screw, so hook up for the emissions test and then tweak to get reading, you have to give it around 5 seconds after each turn to sort itself out, then just turn until set.
Believe me from your co it will be so much nicer to drive when set correctly, as 5.8 is like having the choke on!!
Let us know how you get on,
