How to remove speed cut off

[hasway]

Hi,
I just bought my 2003 Tahoe few weeks ago. I realized that there is speed cut off while I am trying to gauge the top speed at 104 mph. Anyone of you guys know how to get rid of this speed cut stuff.

thanks

Black bear tune will set ya up.

 

[wmgood64]

some of the programmers you buy can change that too!

yours cuts at 104? If i remember correctly, i thought mine cut out at 90... but i could be wrong....

IMHO, your best option is drop dollars on a Black Bear tune, not only will you lose that speed limiter, but you will get there faster too

Technically, I believe the governor is suppossed to be 98mph IIRC. But like others have mentioned, you can change that by either a handheld programmer or any custom pcm tune such as those performed by BlackBear Performance.

It is supposed to be 98 but these things seem to vary alot. I've driven a stock BMW that went 165 when the cutoff is supposed to be 155.

stock, mine cuts off at 109mph... =( cant even hit 110 *sigh*

 

[tybardy]

ive done 110, never been faster in my truck though.... to scared of cops

i've yet to wrap up my yd and see where the cut is...hmmm...

the 5.3 silverado's are governed at 98mph, not sure what the tahoes are.

Thanks folks. FYI, I am now working in Saudi Arabia, and some of the peoples here driving like in German Autobahn. When you are driving 100 mph here, don't be shocked when you see this Hyundai Accent flashed headlights to you at the back, ask you to merge right to slow moving lane.

And here, it's tough to get aftermarket parts for GM truck too.

Anyone have pictures of this Blackbear tuner, is it handheld programmer stuff? Can I buy it in eBay?

hahaha BB is a custom tuner and since you are in Suadi... you may not be able to get his custom tune, but you could get his pre-packaged tune....

I run from Cincinnati to my parents lake house in Tennessee every other weekend with my buddys to do some wakeboarding. Me and this newer mustang were rolling together for about 2 hours going about 85... we had a few open streches that we got up to like 98-99 but then I would shut down. Being Lowered, stabalized, and the sway bars makes this thing feels smooth as glass at high speeds. The only problem is the pot holes with the 24's going that fast makes me think i could bend a rim.

The guy that tuned my car (383 stroked and T-trim supercharged camaro) is going to tune my truck as soon as I get my heads - cam in. So I will be able to go a little bit faster. i dont think Id ever push it past 120. Its just to much truck to stop.

shut down

 

[tybardy]

when yours "shuts down" does it drop the speed once it hits the governer? thats how every other car/truck i have owned worked except my hoe... for some reason, the truck would just hold at 90... now that Im tuned ive had it just over 100 and it wasnt slowing down (i was just to scared to get it up there, to many cops)

 

[BlizzardX23]

must be a GM thing...cuz like you, every vehicle I've ever drivin to governor...it would kill the fuel...till it drops down in speed...but my 'nali holds a constant 109....thats just the way they work I guess...


I know it goes faster cuz I had a Superchip programmer for a short period of time and took the cap off...I was doin over 115 at one point

 

[Robert.K]

Put a superchip flashpaq tune on mine and I havent hit the cutoff yet. I know I do atleast 100 to work almost everday! and with 24's on 4x4. dont go faster then that, cause it is alot of truck to stop.
