I was wondering if there was a speed limiter on my 89 RS and if so where is it, and how do i take it off? My speedo says 115 mph and before i try to get it there i want to be sure i will be able to. Also is a 5-spd on these cars rare?

 

5 speeds are rare in 3rd gens IMO, be glad ya have one

but the car is probably speed limited to ~ 118 or so

 

anyone know if you can remove the speed limiter on a 97 3.8L Auto?

I don't have a speed limiter on mine

 

Wolfie... went to the site. How's it working on your ride? Do you have any other modifications? Doesn't sound like a bad deal.

 

i thought that was just for V8s?

 

does wolf have any other mods , LOL yeah , just a few.... (it will hang with a Z )

 

mine works great ( i have a z28 guage cluster on my car to take advantage of it) tho fastchip did mine,that place will do the same thing for less $$$

 

Your speed limiter is in the pcm and is there because of the tire's speed rating. It is government mandated. Unless you have Z-rated tires you should be limited to about 108 mph. The only way around this is an aftermarket calibration. Some people bought 5.7 cars with non-speed rated tires thinking they could upgrade the tires and get rid of the speed limiter with a new cal. from the GM dealer, they were wrong. Check with aftermarket calibration manufacturers.
