New Daily Driver 56k=Owned

[TheBlizzard]

With my mods I was seeing 0 KR running a 3.0" pulley on 110 octane gas. All of these cars are different though, some knock more than others. I scanned with a stock pulley all the way up. I saw a lot of KR when I was running stock exhaust and was trying to run a smaller pulley, when I put a full 3" exhaust it went away totally. I saw 1 or 2 here or there. On pump gas I never ran lower than a 3.5" since it knocked like crazy.
