    Got a very slight misfire

    happens on full boost, like a pulsing ?

    it has 10 gallons of fuel in, so it isn't that, it hasn't ever had 95ron in it so it isn't that -

    it was serviced (plugs, oil, oil filter) 2500 miles ago.

    So the only things i can think of is:

    Oil starvation (i.e lack of oil in it, will check when it is cold)
    Turbo pipe (although i recently replaced)
    Worst thing is the torque convertor, which i hope it isn't

    Any other thoughts -

    Could be many things, an air leak, is possible, plugs could still be worn or one is failing, you have a bad batch of fuel, HT leads are breaking down, Dizzy cap and rotor arm failure.

    Hard to tell but theres some to go at

    I have had the same thing. Mine was the plugs - do you know which plugs were put in? Under full boost she would flicker. Only other time it happened was on a bad batch of fuel.

    Key thing like J said is the ignition. Changing the dissy cap and rotor is cheap and easy to do (get some tippex before hand). If a HT lead has failed then it would be evident throughout the rev range, IMHO - as I had a failure on my 740. HT leads either work or they don't. Suggestion - BKR7EVX plugs from NGK - about £35 for the set of 5.

    Justin taught me a lot of this - which is probably why both answers sound the same
