I discussed that with my tuner, he said for basic breather mods the vvel won't really come into play. Tuning with uprev vs ecu tek won't really net you much gains as you see with his dyno, it's when you either go boost or you're building your heads and installing a much more aggressive cam that tuning with ecu tek will start to shine over uprev.
