Just curious what experience everyone has. I am really looking to get rid of it and move to another tune should I find that the issue is with the tune.

Please share your experience. Considering going to Evolve or GIAC at this point.
That's exactly how I felt when I had Cobb (early) Beta running for a few months. Not only was power gain meager, it was very nonlinear and totally transformed (adversely) the behavior of the car. Dyno proved my sensory findings - a mere 10whp peak gain (same as what my midpipe delta was), and tq graph was extremely seesawed and spiky, lots of ups and downs (though in fairness to the tuner, they did advertise a 4% gain which was exactly that). I believe that tune has been improved in its current state, but have not tried it as I have a bespoke solution, which I would highly recommend. PM me if you like further details.
