Are you tired of the guy with a leer who asks you if it is true that old truck drivers never become impotent, they just get a new Peterbilt??



Forgive me for I know not what I do.
Your lucky over here (UK) we're restricted to 55mph before we hit hills.

If it's mechanical then it can be as simple as adjusting the throtle cable on the engine sometimes there is a stop bolt that stops the throttle opening fully. Even tightening up the throttle cable can give a little more power.

if you own it then you can pay to have the computer reset.the problem may be more gearing and engine size for the load you haul.as well as the steepness of the hill.i drive a 500hp truck that does 75 on the flat and 55 on some hills and 65 on others,there are lots of variables
first it matters not the cab maker ,the important information is ENGINE MFG. and design and hp rating. the trouble with getting them "TURNED UP' is if you pay someone to do it and it ain't yer truck hammerhead is exactly right ,the tech doing your oil change will turn it right back down,and if you buy all the stuff you need to turn it up yourself you still need the secret code.now the reason i know this is I used to drive a big truck myself and I bought the scanner to turn it up and when i hooked up it asked for the code and until I paid a tech that was quitting a hunred bucks just for the code the scanner and cartridge were worthless,so if its not your truck and you are going to be in it a while ,GET THE CODE FIRST ,if you are just leasing the truck while yours is in the shop or something just tough it outPeterbilt Governor?
Well better find someone with a laptop and the program to reprogram the computer.

Most likely the next time Ryder services it it will be reset to 65 as that is what they want!

Also IF you get into an accident the first thing they are going to do is check the computer to see how fast you were going, LOL

Also if there is a qualcom on the truck they can tell how fast you are doing while you are going down the road and in some cases can reset the speed limit through it LOL.
