Using new factors supplied by Beanjapan, I did another standing 1/4 mile. HP figure is very close to advertised number. The app I'm using isn't 100% accurate, but it's darn close. However, the dyno numbers aren't really the main thing for me, I'm more interested in my data logging figures above. Those values were recorded from the ECM, real time, using my scanning equipment. It's very accurate. I will have hard data as to exactly how much timing is added when I do apply the tune.
The dyno app thingy is just for fun, and is surprisingly accurate.
