I have a 20g turbo and i recently increased the boost from 20lbs to about25-26lbs. I noticed i get 3-5 degrees of knock so i brought the timing down. My timing is at about 3 degrees at 5-7000 rpms. If i run my timing any higher the knocking starts I use 93 octane fuel all the time so i was just wondering if extremely low timing the norm when running higher boost?
