That is relatively normal and expected operation. The controller is giving ALL motors the exact same voltage (PWM to be more exact). The tach reader motor is giving feedback to the controller loop. When you slow the tach reader- the controller gives MORE voltage(PWM) to all motors until the tach motor achieves the target rpm.
What it means is- your other motors either have more friction or more load and your tach motor wheel set and gears are extremely free - but ALSO may not have good traction.
Again, this is somewhat expected- the system is working as intended. You either have a traction limited situation (clean your track, ensure your wheels have good clean fresh traction tires) or reduce the load (drag or number of cars).
