Yes all new tundras have the speed limiter. Not much we can do about it.

 

Don't know if this is true or not, but brother in law of mine who owns his own auto shop and always has the latest, greatest gadgets told me he could use a new programer he got to link to my Tundra computer... from there he can access a lot of the factory settings like the speed limiter, seat belt buzzer, etc. and turn them off or on!

He even went so far as to say that he may find certain options on the truck from the factory that are installed but "turned" off like alarm etc.

Supposed to take the truck in to the shop in about a week or so... Hope this will actually work on the Tundras... Will let you know all know if works and what brand etc.

 

So what happened? Did that work?

 

Yes please let us know on this thread!

 

mine does 115 then just sits there and cruises my feels like it drops cylinders

 

Man, that would be sweet! If there's anything out there that'll let the ponies run free, I want it. There are times when I'd like to break the sound barrier.

Thanks for your post, and be sure to come back and give us the details if it's true.

 

i got to 120 in mine but thats the highest it gos then it sites there

 

Same here, Need i fix soon

 

Have not been able to try it out yet, but...word on the street is that the high end engine scan tool (OBD 2)? should be able to remove the limiter and the seat belt chime etc.

My truck was in the body shop for a while because some ahole hit my back bumper. I should be able to hook up my truck up soon.

Does anybody know if its true?

 

Does anybody know if its true?

Man, I hope so!

 

In case cops are chasing you. (or Tony Soprano)

 

Why is it I wonder that some top at 110, some at 115 and others at 120?? Mine tops at 110. I'd heard of others at 115 (can be seen on youtube actually), never seen 120 though. I thought originally that the US models were topping at 115 and the Canadian models (like mine) top at 110 (178km/h). Seems kind of odd for a mfg to have so many different limits on the same basic truck. I wonder if it goes by model line, like reg. cab, d-cab and crew max?

 

Prob has most to do with the countries legal restrictions and safety limits.

 

Just what we need....high profile 4x4 trucks going 140mph down the hwy!! Ever driven an old muscle car that would go that fast??? They start to lift and steering gets real loose because they have no down force and there is a ton of air rushing under the car. If they weren't so heavy they would fly..LOL. Oh well..............if my truck would go that fast I probably would try it once or twice and then a third time for good measure...he he he.

 

Howzit Hawaii,

Let me know if the braddah in law's computer can increase mpg. I would be interested.

100 mph or greater in FL is reckless driving. Go directly to jail, bail, see a judge. No thanks. Worked all that out of my system over 20 years ago.
I can tell you this. For some real excitement, take a street bike,(not a cafe racer type), at least a 650cc, down a gravel road, fast as you dare. Over 80 mph, things begin to change. The gravel becomes a fluid, the bike a jet ski. Faster than 85mph, you can turn the handlebars all the way, either way, the bike will continue forward in a straight line. You can ride back and forth over that center hump of gravel like it's wave in the water. Just lean a little, the bike will respond. Don't use the front brake though, it will all end in tragedy.

 

Check the speed rating on your tires before you go much faster.

 

This is an important factor that I think is overlooked. I can say that I have'nt always abided by these though..

 

Has anyone found a way around the limiter yet?

 

it's not worth getting a ticket , getting in a wreck or killing someone else.

 

Some of us would like the option to be able to upgrade the suspension, fit it with racing tires and rims and run it at the track. I'd like to take mine out to Bonneville during speed week and she what she'll do top end.

No ticket, and hopefully no wreck or killing someone, but if it happens it'll only be my truck and me who gets damaged or totalled.

 

I Guess If Your Have Your 5.7 Tundra Chipped, Lowered And Run Speed Rated Tires, You Can Achieve Speeds Like The Supercharged Ford Lightnings And Srt-10 Rams (over 140mph) Without Problems.

 

The official speed limit listed in the manufacturers spec is 111 mph. It either retards the ignition timing or restricts fuel delivery after this speed is reached. I've done it in my 2007 & the behavior under the hood is the same as when you run out of gas. Since most Tundra owners are generally a brighter bunch, I'm not totally uncomfortable with these guys running their Tundras faster than 100. Kidding (about the uncomfortable part).

 

I think these trucks will do 140 easy.. when i tested mine out i had good torque untill i hit the limiter at like 111 and the speed incresed from momentum to like 120-125....thats good torque at that speed... now once i put this s/c and headders then program it in... you can just start calling me the silver bullet!!!!!!lol first 08 tundra to hit 200mph...lol

 

Usually 300 (iah) RWHP won't push a brick that weighs over 5000lbs past 140. I would bet bone stock these would run about 132 to 134 max.

Heck the SRT8 Challenger only hit 152mph (if i recall from the Top Gear episode) at Bonneville and they put down between 348 to 362RWHP depending on the dyno...

 

Any new information onthis topic?

This thread should be a sticky!

 

Over sized tire's should also be considered, the larger over all diamater messes up the speed if you dont re-cal. When im doing 120km/h on the clock my gps say's 136 thats with a 35" tire

 

yea i have 35's my truck pulls back at 108mph on speedo gps says 119mph though

 

I want my seatbelt chime de-activated. I cant even let my 12lb dog ride in front with me cause I gotta hear that stupid thing. Would love to know how to get rid of it other than sticking a dummy belt in there.

 

Try a search on that subject. They have several threads on deactivating the chime.
