2005 Columbia Detroit governor at 65MPH - How can I increase speed

QUALITYTRUCK you have received 128 thanks and that say a lot. check your message box.

 

Turn the key quickly off then back on while foot is on accelerator, it will go past governed speed. But will have to do it every 3seconds

 

Turn key off then back on quickly while accelerator is all the way down. I used to do it when I was governed

 

I paid 140.00 3 times at dealer to up the road speed. Batteries died now set at62 mph I contacted detroit diesel no response yet. Don’t know what it keeps going back .

 

You're gonna drive an '05 Columbia over 60 mph???

Farewell and ado to you fair Spanish maidens.........
Farewell and ado to you maidens of Spain.
For we've received orders to sail back to Boston...........
And nevermore shall we see you again.

 

I love my 07 Columbia no matter what I can’t seem to sell it. But I’ll tell you it’s one of the faster built/tuned higher hp otr trucks out there. Pull up lol

 

What's wrong with over 60mph?
