All I know is looking at your log you're already running on a the leaner side of things and fuel trims are close to being maxed so you could easily end up running even leaner without some revisions to the base map.
Thanks, I'll go look at the Spl. Str. forum. I did see that the BMS JB4 BEF leaned the AFRs on the top end so I think I'm going to change at least the top end in the "load" areas I'm in back to OEM, and see what happens.
