2019 ram 5.7 Hemi top speed
This big Horn 5.7 Hemi tops out
at 105 mph
Is there a way of getting more
speed if necessary?
Though this would be more then
enough speed under normal
circumstances.
I however have had time when I
need more speed to survive!
Is there anything I can do?
If I bypass mds system by
placing in tow mode will that give
me higher speed without limiter
shutting it off.

The top speed of the vehicle is controlled by the PCM. You'll need to have a tuner shop program a higher speed limit into the PCM. Hope that helps! Jim
