i have a 1998 gmc z71 1500 and i have noticed when i need to get out of the way it has wonderful pickup to 100mph but then it seems that the great folks at gm decided for me that i dont need to go over 100mph and so the truck shuts down until i reach 94 mph than it picks back up. i was just wondering if anyone had a cheap solution for this (other than unpluging the speed sensor on the tranny).

tryed that my abs and the tranny shift went haywire.

so any help would be app. :puke:

a programmer can probable remove it, but do you have speed rated tires and superior brakes? hope so for the rest of us.

You cant unhook speed sensor because the PCM needs input to run the engine & for transmission to shift.

I dont know of a state that has a 94 mph speed limit. Slow down and save your life and others.

Most any programmer can change it, but NEVER change it to above the speed rating on your tires, or you die.

If you all travel the interstates at night, those semi-trucks run dam* near 100mph so I could definitly see having to run at least that every now and then. My 285/75 BFG's have stood up to pro-long trips of 90+mph when I travel out to Texas. The only way I can think of to get the limiter off is to buy a programmer or find someone that will hook you up and change it for you. The only tires I would be scared of going that speed would be some nobby mud tires. Any All-terrains and Street tires I am sure would be fine.

Now I know why my insurance is so high.... Unless you are running from the law or the law man, why in gods name do you need to drive faster than 90MPH? Again, these are trucks, meant to haul, tow, etc at SAFE highway speeds they are not designed to be sports cars. Remember speed does not kill, it's the sudden stop. Good luck and make sure you have your organ donation paper work filled out.

Had the same deal on my 98 Tahoe. I don't want to travel at that governed speed, but may have to pass something. Used a Hypertech programmer to up the speed limiter. It is sitting under my desk if you would like it. Will not work on my 02 Suburban. Do watch your tires' speed rating. Steve

Semis going nearly 100mph? Sorry, but I HIGHLY doubt that, seen as how most semis also have limits. Sure they can be overcome by programming, but at least here in Wisconsin, it is against the law for dealers to remove the "speed barriers" unless it is on some type of Police Vehicle. At least that is what I was told when I asked around just out of curiosity.

hehe hate to break it to ya, but if hes going that fast, there wont be anything left to donate, aside from the pools of blood you may be able to save by soaking up with a sponge, or a shop vac. I like racing as much as the next guy...but like someone else said...these trucks were not built for that type of movement. If you want to go fast, buy a sports car.

firefighteremt3100 couldnt have said it much better. I have had many trucks and never had on at top speed to have the rev. limiter cout me off. Come to think of it i dont think i have ever had on over 80-85 and that was to pass.

Want to go fast by a ZO6 Corvette and go to Wyoming.

Indeed darwin material. A pickup tire blowing out at 100mph = bye bye!! Ask the Explorer drivers that couldn't control a 70 mph blowout. Most semis we see now don't exceed 60 mph anymore because they have gps units sending data back to dispatch to monitor fuel consumption and speed, the only ones speeding are dumbass owner operators who don't realize how much fuel they are wasting.

      Electrical Problem - solved

      By CNH-320 · Posted

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.

      “It should be recognized, however, that there becomes a point where fuel economy oils do not make much economic sense for the end consumer—we talk about a fuel saving of ~€100 compared to a risk of €1000 Euros if the oil is too thin and causes increased engine wear rates. However, the benefit of these oils accrues to the car manufacturers. If their vehicles can save 1–2% fuel by using a special fuel economy lubricant, then that OEM can drastically reduce the amount of fines they need to pay.”   I liked this and the following paragraph as well but it’s really only touching the beginning of the benefits OEMs see from spec’ing these oils. After you factor in “out of warranty” service work and new car sales when these engines fail before their time, it’s a good racket for them. Just because you're paranoid doesn't mean they're not out to get you!
