OK, well i did exactly as ben said (put in the stock maf, got a stock MAF voltage table, then figured out the housing sizes, multiplied the table by the difference), it smoothed the idle way out and was quite rich while it was at high idle, which was abnormally high (2k) and it hung there for a good 10-15 secs. When the idle came down it then went stupid lean (1.6), then the gauge just went full lean with no reading.....i had to shut her down. Here is the log and tune, as brief as it is. Any ideas? im pretty sure the BA5000 is bad, it did seem way happier with the stock MAF. Thanks for the advice guys, at this point im open to a remote tuning session to just settle my lean condition, it honestly just needs to be cleaned up once i figure out the lean at idle issue, which i can take care of that stuff. i need to learn anyways, but this lean idle thing has got me clueless.....
