Once you get the VE tables dialed in, plug the MAF back in. Now tune only the MAF table to get the fueling back to the same range. I have tuned probably 50 of the Black Box Vortecs in this manner and they run great for what they are. 0411 or P59 is much more accurate and just better all around even out of the box.
