Since ive been tunning, Ive only been looking at my BLMs. Ive got some rich spots that come and go, itll stay bellow 120 for quite a while when I first head out (like 111 for the first 5 mins), then hang in the low 120's.
Now I start looking into the INT and notice its really close to 128 all the time! say like 126-130.
What do I do?
I tried locking the BLMs (setting the min and max blms in the constants to 128), but it didnt work, they still wander. I gotta try burning that chip again because something else I changed didnt take place.
Am I on the right track here?

When the INT stays near 128, it means your BLM has adapted properly. With a warm engine, and BLMs in the low 120s, I'd leave it alone, as it means the VE table or MAF tables are just slightly rich (but the closed loop is correctly making 14.7).
When it goes to 111 when first getting it going, it's probably just your purge canister purging the fuel out of the activated carbon (charcoal basically). Could be some other warmup enrichment that's in effect too, but don't worry about that.
The stock bins usually have a limit for open loop that doesn't allow any enleanment from the BLM until closed loop starts. This is the safe way to do it - have BLMs below 128 when warm, and then use 128 when cold startup to avoid lean at all costs (it's for smooth running, mostly, to avoid surging or stalling).
