Im never sure about tuners dyno's, they always want to show a good result after any work, not only that you have nothing to compare with.
I like Dyno shoot outs, same dyno, no biased tester (who would normally be the tuner validating his own work) to influence reading or frigging correction factors, purely a run, same ambient conditions only difference being the bikes. I've been to a few where folks go on about how a tuner previously had some amazing figure, then it goes onto the dyno shows a whole load less than they expected. They claim its the maybe dyno or ambient conditions, then someone with a fairly standard bike makes more or similar power.
I enjoyed the last one I took mine on, my 05 10R made the same as a K6 tho with similar mods and just pipped a stock ZX12R making a genuine 160bhp at the wheel on a hot 28c sunny day.
