You need to look for the following things in this order:
1) Octane (tune once for street gas, and a second one for the track).
2) Compression ratio - is yours too high for the octane you're running?
3) Once you have the octane decided on, start adding fuel in the cells you're getting KR hits on.
4) When adding fuel in that cell no longer reduces KR, then start backing the timing off in that range.
Remember, the higher Octane you're running, the more timing you can get away with. That's why I say settle on what fuel you want before making adjustments.
And you're right, VE tune has nothing to do with this particular situation. I know a couple people that are running 13's with stock VE and only doing MAF adjustments.
