Sorry to revive this thread, but thought I would inform everyone that I finally got some spark knock, only happens on WOT and 4k+ rpm, it sounds awful I found this video incredibly helpful for determining the sound. https://imgur.com/a/spark-knock-ping...nition-QLKIbiR
I did put 91 octane in it but it ran horrible both tanks only lasted me 100 miles and it made no power, so I put the lower grade back in it.
I am inclined to give it 91 again but it needs to last a little bit more than 100 miles lol. I am going to fill up at a different gas station this time and put their premium in it and see if it handles it better.
I have the timing set to 12BTDC currently, when I put the higher grade in I will advance it. It felt like the engine had retarded timing the whole time I was driving it with the 91 in it. Again I don't have any experience in engine tuning so there could be a completely different reason for the poor milage and no power on 91 like I got bad gas from the pump.
Also I bought some octane booster as a temporary fix until I can put a higher grade fuel in it.

unless you have a tuner to change it.
