noticed a couple of people having a the problem of a flatspot around 2500 rpm like me so thought i have a go at solving it. my first thought after looking into it was auto detonation after hearing a slight tap in the engine so went for higher octance fuel which was v-power + Nos Octane booster (race use not street) which makes it around 105 octane for a more efficient combustion and cant fault the stuff. its an extra £2.50 (335ml bottle) to add to the fuel bill but made such a difference prob gonna buy it in bulk :clap:
