I think i may be experiencing rich knock, my question is how much should i adjust my SAFC? its super rich between 3200-4464, and im still pretty rich between 4676-5516, i notice my timing curve looks nice as soon as the mixture goes to .93 so id like to target that mixture 1st and then see how the timing looks and then adjust again from there for timing

Current setup:
14b @16 psi
stock 450cc injectors
RNR 2.5/3" turboback
Dejon UICP
1g bov
rewired Walbro 190

I'd take away -3 from 3000 to 5500 then add 3% from there on up.

It's all trial and error(hopefully not big error's :) ) Just keep adding and taking away until your happy.

Also you want your timing to end up at 16 degree's.
