Finally gotta hold of Matt.. he now works at VMP. Explained my situation on a desperate need for a revision of his tune. That was on Mon, Nov 4, 2019 at 4:36 PM. Have yet to hear back as of today.
UPDATE: Finally got a hold of Matt, and got a tune revision. Said he lost all his contact info. I'll give him the benefit of the doubt.
Frankly he's a great tuner, better than most of the heavy hitters in special sauce land. Kudos to Matt & VMP.
