in the cruising log, it doesn't even seem to make it into closed loop for some reason, but the highway one seems not too bad. your timing advance needs a bit of love (mostly due to the different cam) but it's a good start.
you should lay off the 100% throttle until it's tuned.
breaking up at high rpm might be due to the fact that someone leaned out your PE tables quite a bit. try this bin instead. i tweaked your timing table a bit too to get it closer, and a few other small things, but it still needs work.
