I think we have different definitions of what a tuner is.
I absolutely agree that shooting with or without a suppressor changes the MPI and increases velocity. The added weight on the barrel and influence on the exiting gasses is profound. Same with, and without a muzzle brake and it's influence on how exiting gasses influence the bullet and barrel rise. Big differences to barrel weight and gas direction has a noticeable effect.
But a tuner is different. Plenty of discussion online about whether they work or not for the reading. I saw one F Class shooter with a heavy match rifle over a few months use one and eventually take it off because it made no noticeable improvement in groups.
Of course I will accept actual experience with a tuner.
I suspect the effects of using a barrel tuner are similar to the technique of adjusting seating depth. Sometimes it really does work, and other times you were already at the best you could do and you make it worse.
