    hope you guys can view these. should be set to public. any feed back anything like that, let me know. like what i should be looking for in all the original categories. also, check out the dyno tune.. it peaked out at 311hp 280tq. that was surprising. way over what i was expecting, even if just for a second.

    I'm assuming you did all of this on the Cobb AP and on the roads?

    So from my knowledge, if your car is 5 speed it's best to do a 3rd gear pull from 2500-6500(i think)
    Yours is close enough.
    You have a small amount of fine knock learn.
    But, from what i have learned, as long as it isn't a lot and isn't higher than -2.8 then you should be fine.
    Aside from that of what i know they look good
    When did we stop being who we want to be, and start being the person the world told us to be...

    It intercepts what the computer is reading, so very accurate when it comes to DATA logging. However, the "dyno" portion you are talking about is not accurate what so ever. The AP is NOT actually a dynamometer, it is merely a guess. In order to get an accurate HP reading you need to take your car to a shop that has some sort of dynamometer or dyno for short. This will be able to more accurately tell you your horsepower and torque to the wheels. Keep in mind that every dyno is different in the way it calculates horsepower from torque. This means that you could have one dyno telling you 275 WHP and drive right off that dyno an onto a different one that will show you your WHP is 260. I would recommend reading the thread linked below:

    Dyno FAQ

    Otherwise, your data logs look good to me. The very little bit of fine knock learn is just fine. Especially since it's correcting itself just moments after the event.
