Yes, but the engine is internally stock in part so that it wasn't overwhelming to learn to tune on it. When my setup becomes a bit more aggressive I'll likely do some tuning myself and then haul it in to Payn for that last 10%.

If the version you saw was pre-1.03, it's a whole new ball game now. 1.03's interface is, imho, more intuitive and accessable for the amateur tuner (speaking from experience ).

On the downside of 1.03, AEM got full sets of sensor spec sheets from Honda and replaced their self-made calibrations with this new data from Honda. All the specs are wrong. :squint: The ECT reads ~30-40° F high, and the AIT ~20° F high.
