    I was pulling 5s when the outside temp was cold so I dread to think what it was doing at the weekend!

    welly, when you did your tweaking, what level of pull were you left with?

    I saw upto 10 when on max advance with revo. Set to 7 now and get around 6 or so with 99 RON and a fmic. Thats the bam.

    See look, that's interesting. I've got REVO and turned up the timing advance to max level 9. Because I've got the large port head which flows better, I still wasn't getting ANY timing pull, even with it cranked up.

    So now running 2.25 degrees above the max of the map, and getting 2s and 3s which I am happy with.

    i can live with occassional 2s and 3s. i got the willys when i saw a 5 pop up when i experimented on 2.25*

    with 2s and 3s ive got headroom for "less than ideal" conditions. may even consider colder plugs. or i may just leave it lol

    That was what I thought, 2s and 3s I can live with. I did take it up to 3 degrees advanced and was seeing 6s then. Would of been OK, but rather not push it after blowing it up once already....
