You really need to post up/link us to the
other guy's mod list and/or dyno (log file)/tuner at this point.
It simply could be that the other guy's supporting mods aren't up to the task and the tuner had to pull timing/power to keep things happy. Keep in mind Harrop's flex fuel kit includes 1100idx's. Also, if the guy is on the stock clutch or stage 1 equivalent they would have to chop the gains to keep it from glazing.
Lastly there is a big difference in tuning. As Justin posted, variations can easily effect number. As can what the car is being tuned for. Tuning a car for max power for a few runs on a dyno is very different than tuning a car to run 30min track sessions back to back. A lot of tuning companies will also play it safer when they tune a larger volume of cars or if the user isn't very wrench handy. It's very common for a build to go wrong and the first bandwagon everyone hops on is it was a bad tune...

If you want to feel better here is a dyno pulled for the UK forums. Member MartinT and Mark's which were tuned by the UK's Abby Motorsports. And an unknown users car tuned in the US by TRL. They are all hitting just below the expectations posted above without e85, a smaller pulley OR larger injectors. 260WHP (300bhp/223.7kw.) This slots it right in between Harrop's advertised Stage 3 and 4 packages FWIW.
