Well I was watching my afr and knocks. I was running extremely rich and no knocks up top. My old tune I was running 17 degrees of timing this time I was at 10 degrees and added 5 degrees with live tuning.

What sucks is I made 421hp on 14psi of boost with a boost leak a couple of weeks ago. I fixed my boost leak and ran 21lbs this time and my first pull was only 401hp

Timing is everything lol
