This chart shows a comparison of the 7th iteration of the Nefmoto community 2.7 tune with the stock B5 S4 tune and also a log I have from a different APR chipped car.  The APR car is not mine, nor is it as extensively modified along the intake and exhaust airflow paths, the point of putting the data on the chart is to give a sense of about where the Nef7 tune falls in comparison to two other tunes that have widespread use.
