I'm running a stock 2g mas, dsmlink, aem 3.5bar, and used to have but recently stolen aem Uego wideband.
I just tried a 93/110 mix for fun, and it allowed 27-28psi with 23deg of timing with no knock issues, but recently I read that you can be dangerously lean on 110 and still no sign of knock through dsmlink. This is why I won't be trying that again without my wideband fixed.
