Question for those LNF gurus. I am currently doing logs of my current tune. **Attached below
I am running a custom tune (20 psi on oem k04) on a completely stock 2009 Cobalt SS. I have achieved as high as 17 degrees of timing advance on several runs. In the log attached, on my final pull I saw 3 degrees of knock. Looking at the given log below, do you believe this to truly be the engine pulling timing or burst knock? All input welcome!
