What is the process for disabling the speed limiter on a Chevrolet Silverado?

★ Top Answer
Disabling the speed limiter on your Chevy Silverado is not a common option for drivers. The limiter caps the Silverado's speed at 99 miles per hour by utilizing the truck's ECU along with gear and wheel sensors. Removing or modifying this system typically requires costly firmware that can impact the ECU. Referred to as "tuners" or a "tuner chip," this technology can come with a high price tag, sometimes reaching close to $9,000. Another way to bypass the limiter is by disconnecting the wiring in the Silverado's ECU that manages speed controls, but this information is not usually readily available from manufacturers. A more cost-effective method to alter the safety controls involves installing additional devices that interfere with the ECU's readings, although compatibility with all trucks may vary.

One method involves buying a Super Chips Flashcal or Flashpaq device. Before anything else, it is essential to get a two-piece driveshaft for the 2WD crew cab since the one-piece shaft is unusually long and will quickly break once it reaches its critical speed, making it flex like a jump rope. If you have a regular cab with a short box, you might be fine, depending on the rear differential ratio. I suggest looking into critical driveshaft speed and recognizing that breaking a shaft, as I have experienced, can be a costly lesson. Take caution and best of luck.

In the world of racing, a price tag of 9k is typically seen on high-performance vehicles. A bully dog, on the other hand, can be purchased for around 300 dollars, while there are models available for even less, at 200 dollars or below. Keith F. makes a valid point about the importance of considering the driveshaft. The issue arises when many individuals push past the speed limits, with some maxing out at 99 mph, like my truck. When adjusting, it's advisable to only slightly increase it to around 110 or 115 mph for improved highway performance.
