Imo stacks only move power around. Long stacks more torque short more top end. But its small.

The problem with velocity stacks that i have run across is that with a hand held tuner you can not change your AFM you need a PC5. When I did the velocity stack upgrade and took it to a tuner he said with a PC5 you can only work with 4 of the 8 injector. It was a older mobile dyno so I'm going to try another tuner because this guy definitely had some problems like he blistered and pretty much ruined my tire.

Iv never had a dyno ruin a tire. Very odd. Also unless your over 205hp at tire you can use a pcv on single row of injectors. Then you add a module to use second row.

If you do not strap the bike down on the dyno wheel properly, it can move back and forth enough to hit the edge of the dyno wheel guards. Then if the dyno operator constantly hits the Dyno Brake to stop the rear tire, it can lead to over heating of the tire and cause the blisters.

Thats why im saying odd. It has to be user error but must be a inexperienced operator
