Default after using fuel trims to dial in VE table in CL SD..

now, when i plug back in my MAF and enable it; are the fuel trims going to go crazy again? should i leave my MAF table alone, since i dialed in my VE or adjust the MAF by a certain percentage based on the fuel trims being + or -?

Yea I had done it the old way with the spread sheets, but this is much better, easier and much more correct. I use my WB for my PE curve, yes curve.
