. . . from the Alltrax website:

"The DC electric motor controller (speed controller) interprets
the battery to the electric motor. As the throttle is
increased, the motor controller output power increases the
motors speed and/or torque. Some controllers can also put
some energy back to the battery called Regenerative
Braking.

A controller will not increase your speed. Larger tires, different gears, or different motor will.

By itself you may be right but a higher amp controller will increase speed in combination with cables, motor, etc. more than if a stock controller was used.

If that were the case it would not be the 5mph gain the OP asked about. Maybe 1-2 mph tops in your scenario.

I think you need to break it down or clarify a few statements here to satisfy the original question.
Will a bigger speed control increase speed?
A bigger speed will increase the amount of amperage a motor can pull from the battery pack at a given time. That's an important statement. Most people think speed controllers feed motors amperage but they do not, they allow access. The motor will pull 100% of the available amperage it is connected to... In our care that's the battery pack. The controller limits this quantity.
Increased Amperage increases motor torque.
Increased Voltage increases motor speed.
SO simply putting a bigger controller on a series cart will not in crease speed. It will increase torque which allows you to effectively turn taller tires or change to taller gears which would increase speed.
Increasing the voltage and the amperage would increase torque and speed.
Some aftermarket DCX controllers eliminate the rpm limit of stock controllers, this is perceived as an increase in speed but in fact is just a limit removal.
This is why the 48v conversion is so popular in series drive carts.
I hope this helps.
