FX Impact M3 pellet port vs. slug port air efficiency?

[Der_Berend]

Is there a difference in shot count between using the pellet port or slug port for a given velocity? They probably included two transfer ports for a reason, so I'm curious what the benefit of using the pellet port is as compared to just using the slug port even in tunes where the transfer port isn't the bottleneck.

USE SLUG PORT WITH A PIN PROBE GETS YOU 30-40 FPS MORE FPS . THEN SHOT COUNT WAY BETTER AS YOU CAN TUNE THE GUN LOWER POWER AS IV FOUND OUT, YOU WONT SAVE ANY AIR BETWEEN THE 2 IF THATS WHAT YOU MEAN VALVE GETS HIT AIRS RELEASED

Ernest Rowe has excellent video optimizing air efficiency and max power.

I would leave it on the slugs port and turn everything else down it really depends on how fast or what fpe you want high power=more air
