Getting knock at low boost/running lean/FT issues

[16vdohcturboawd]

My first problem is my low fuel trim is out of whack, its running 118.7% so im running lean but I cant figure out why. My mid and high trims are both 100%. My 02 sensor usually stays around .7-.9 until open loop then cycles between 0.01-0.8. Also once I get on the gas it goes right to 0.9. Second problem is im getting knock lots of knock. I can free rev in neutral while parked and pull 1-10 counts of knock, usually once I let off the gas, actually I reved to 7k on one log and got 224 counts of knock. Im also getting knock on the road but usually at part throttle or while lugging the engine. I dont want to do a WOT run yet because if it really is lean I dont want to burn anything down. Also I checked my plugs and they were on the white side so I suspect it truly is running lean. So far the only thing ive ruled out on the knock is heat soak, I have a FMIC and its like 25 degrees out so that shouldnt be an issue, im also running 91 octane the highest I can get around here. Ive done a BLT and havent found any major leaks. Mods are as follows,

Punishment FMIC
Walbro 190 not rewired yet
stock 14b turbo
hallman MBC with it turned all the way down, only boosting 11-12psi
2.5" VRS turbo back exhaust
dejon intake pipe.
ngk plugs gapped to .028
new fuel filter
new ngk wires
stock mas
