How helpful is logging in your runs and then sending them to your tunner. I use pcmforless and was wondering if sending him my loged runs would help hime tune it better. Thanks

 

Of course it would help. They can get pretty close on the 'common' setups such as hotcam and stock heads, but the not so common ones they just can't get with the same accuracy. Data logging lets them see everything that the computer sees, so they can get the tune a ton closer.
