With the accelerator depressed all the way to the floor what is the maximum speed that this pickup will travel at with a well tuned 4.3 liter engine with an automatic transmission?
 
youll get control issues above 90 or so. If that wasnt the case it would go 130 easy.
 
Unaltered, the truck has a speed limiter set at 100mph. You can remove the limiter with a computer chip.

The vehicle has a speed limiter of about 98-100mph. When the vehicle reaches this speed, the computer cuts power to the fuel pump causing it to lose speed. Once the vehicle drops below a certain speed, the fuel pump will resume. This can be modified by your dealership (although many won't do it for liability reasons) or by handheld tuners, tuning software such as HPTuners, or if you know someone to the GM Tech2 scan tool used by all dealerships.
