did I post the wrong graph. From what I see, the interval is set at 20 on both Y-axis. The gains are less than half of that, probably around 5 - 8 hp or lb/fts.

No its not APH I dealt with and you're pretty much on the dot about the location of the tuner, I rather not speak publicly but if you're interested and want to avoid my experience do ask me privately.
I'll check out APH and see what they do. VQ 3.7 is totally different machine than the previous VQ, so a tuner with tuning these engines is a must to get respectable gains across the powerband. Don't want a tuner acting suprised during tuning sessions.
