Help: Mil flash....suspect knock

Okay i'm getting a MIL flash which is most obviously knock but no error codes are popping up. It was dyno tuned and just recently started to get a MIL flashing. I also noticed the tuner put 630cc injectors. I have no idea why since they're 650cc

Mods:
a3
Greddy w/ FMIC
650cc
3" with test pipe exhaust.

I'm new to kpro/kmanager so I'm not 100% sure how to figure out my problem. The MIL flash is only when in boost higher then 5psi. I'm suspecting i'm running leaner than i should.

You have it set so that your MIL flashes anytime knock is picked up by the knock sensor, so that's normal. You can go ahead and retard the ignition where its knocking and see if the knock goes away.

i'll make a datalog with a 3rd gear pull then go from there.

did a proper datalog with a fresh tank of 94 gas and no knock. although i had the datalog running while cruising later and had 1 knock count.

i guess i should ask this too. since there's a mistake in my kal file on the injector size, if i change it to the proper 650cc (from the 630cc currently on the kal) will i have to change anything else like the fuel maps? what about re-dyno tuning?
