I've seen claims form a FocusRS tuner that vdyno is grossly inaccurate because they used their dyno run as the log source, and it wasn't even close to what the dyno showed, therefore VD is worthless. Trying to hack the parameters in vdyno to get an accurate result misses the point & design of vdyno though, so it's not really the way to validate it. Not meaning to discredit the effort of Twisted Tuning especially since I agree that vdyno is pretty accurate, just illustrating the like for like comparison would be dyno-on-the-rollers vs VD-on-flat-pavement rather than trying to massage the input parameters in the app to get matching results.
I'm just about to start the process in the Supra, but here's how I validated vdyno when using my FocusRS. Repeatability was key to me, and this sated my skepticism enough to trust vdyno to feed the data junkie within.
First is the dynojet results of stock compared to tuned:
Second is the vdyno version of those same setups, two runs each (opposite directions, same stretch of road):
