I own a 2000 blazer LT and it maxes out at around 98-99 mph is there any way to remove "the governor" so I can reach a faster top speed ??

I agree - I've hit the governor once, and I don't think it would be wise to go any faster.  Governor is probably built into the ECU anyway - not a place where it's productive to start trying modifications.

Dont listen to them.  Going fast is fun.  I was going 155 in a 67 Camaro built to go fast(acctually just 400 hp 2.83 gears and I have no idea how the tires were).  I have been fast in plenty of cars but I wouldnt go that fast in a Blazer, but the last person is right its built into the ECU.  You could just buy one of those Hypertech programmers type things.  Probaly around $300-400.

The speed limiter is in the PCM's programming.  Most are set to 96-98 MPH.  PCM editing software/hardware or a performance programmer will allow you to modify this limit. 

Here is a screen shot of my HPTuners, showing the limiter on a 2003 S10 4X4.  It's kinda hard to read, but the stock limit is 98 MPH.

^^^  Let me add to this. ^^^

Before doing something like increasing the speed limiter in your vehicle, you MUST make sure that your vehicle is safe enough to sustain speeds in excess of the limit.  Not only must your vehicle be in tip top shape mechanically, but your tires MUST be of a higher speed rating than the speed you want to be going.  Also, your tires must be at the appropriate pressure.  If the speed rating is too low or the pressure is too low or too high, this could result in tread seperation, which at high speed is something to be avoided at all costs.

As always, keep it on the track.  Recklessly exceeding the speed limit on public roads, either close to empty or completely deserted) will only get you or someone else hurt or worse, dead.

AMEN to that, Kyle.  These were NOT made to run at speeds higher than the limit or even near the limit, safely.

That's right. Remember, this is a vehicle with a high center of gravity and significant wind resistance. It was not made to go more than 100 MPH, and doing so on public roads with this vehicle is unsafe for you and for others.

I'm not trying to be preachy, I'm pointing out that speeds over 100 are outside the design limits of this vehicle in stock form, and therefore unwise.

I'm not saying going fast ain't fun. I had my 99 Camaro up around the 210km point once.(Built for it)  The blazer on the other hand I had up to about 150km once. It Rattled and shook so much I ain't gonna do it again(for safety sake) Again I am all for goin fast if the vehicle i'm in is meant for it.

as said you have to reprogram your speed limiter or there are chips out there that you could by to replace the factory ones to completely mod your ecu. yes speed is fun i know i love it myself. but a blazer is not meant to keep up with the imports or muscle cars, so i would not bother messing with it's speed regulations.  

but, on the other hand,if you're going to build the blazer for speed, i highly recommend lowering it significantly. this will dramatically decrease the chance of you rolling the blazer at higher speeds. thus making it safer

I know that GM sets the governor according to the speed rating of the tires on the vehicle.. Heck my old Lumina Z34 topped out at 200km/h and stuck to the track like glue.

I got my old '85 S10 up to at least 140km/h on a downhill (and I was still the slowest person there, lol) but ONLY so I could make it up the other side at more than 60km/h... And it wobbled, and it rode squishy and all in all, not a good idea, lol.

If you need to go in excess of 160kph (100MPH) on a regular basis... You shouldn't have bought an SUV, lol

At least, one with 4x4, if you happen to have it...

Thats all I went that fast (130mph) when I test drove a 02  Z/28 completly stock.  Im just giveing ya crap Ive heard people of people going around 162 (speed limiter) in the LS1s and the front gets really light. Unless the car is built for going that fast (suspension, tires, and aero) I wouldnt go that fast for long, like get there then hold it for a few seconds then let off.

Camaros/Firebirds were governed at 126MPH

Lumina's/Grand Prix's/Buick Regals/Cutlas Supremes/ any other W-Body were governed at 124MPH with the 3.4L TDOHC or 3.8L engines, except for the TGP which was a 3.1 turbo, governed at 124MPH, all other 3.1/3400 or smaller engines in the W's governed at 112.5 MPH

I found my 128mph limiter real quick while I had my SSEi on the track at Watkins Glen.  Was much more fun than my old Intrepid's limiter at 115mph.  That extra 16mph difference on the long straight aways makes the corners really show up quick!!  Will be much nicer when I go down for another go at it after I do some light modding.

Thats depends on what tires they were equipped with from the factory. Z/28s with z rated tires and SSs have no limiter.
