The results of our test are very puzzling, indeed. I shared the dyno plots with AEM and they were quite surprised. When Shawn Church saw it, he was shocked as well. It's just not the way it's turned out in his independent testing.

In any case, we can't complain about 209 hp to the wheels. Consider this - if the dyno plots would have shown the typical 8+hp gain over stock, we would have been looking at 215-216 whp, which would have been inexplicable for an otherwise stock 2.0L S2000. But something tells me that there are other things at play. One theory I have is that the V2 possibly "fools" the engine computer into a more optimized fuel strategy. And since we didn't reset the ECU on the dyno, perhaps even the stock intake system was able to benefit from this optimized ECU calibration even though it may not quite flow as well as the V2. Yes, it sounds far fetched, but what else could explain our very high baseline number? I suspect AEM will be getting back to us with their own theory as to what could explain this, but for now we have our dyno test results.
