    I had exactly the same problem as you mate,a miss fire under load. I changed all Spark plugs(ngk irridium) and coil packs(Bosch) and it's the best thing I've done. Miss fire gone and car pulls like a train. I know it's expensive to replace everything at once but you won't regret it mate.

    Being a remapped car it's essential the plugs be in good condition and gapped at 0.7mm. Coil packs will also show signs of breaking down faster than normal.

    Are all your plugs iridium and gapped at 0.7mm? If not I would do that before looking at coil packs.
    It aint about how hard you hit............ its about how hard you can get hit and keep moving forward!
