Well my buddy calls me this morning. He works at a Stealership here in Mississippi.
If they arent busy they will go drive around a few vechicles for a few minutes just to run them..
Well it was a 2008 ECSB 5.3 LT 2wd... He said the top speed limiter was 80mph..
Only thing they could find a pattern in is that all the trucks with the General Grabber tires have a 80mph top speed?
The trucks with Goodyears and Bridgestones have the 98mph top speed limiter...

Has anybody seen this?
Im goin to go down there when i get home from North Carolina and read the tune off and see what it says.. This is interesting..

 

it would make sense. thats the reason they set it there because of the speed rating. but they aren't the grabber UHP are they? that would be weird. i would be pissed if it was set at 80mph. not that i would go faster than that.

 

i noticed on chevy's website about a week ago when i went to "build your own truck" that you could get an option to have a 70mph speed limiter for fleet vehicles

 

No they arent UHPs... they are the el cheapo looking ones.


These aren't fleet vehicles though... and its 80mph.... kinda silly if you ask me.

 

Maybe they're playing it safe and setting it to match the speed ratings on the tires like mentioned? That's why mine's set to 130...to match the tires.

 

thats what i asked my buddy but all the tires are "S" which is 112mph..
the Generals and Bridgstones and Goodyears all S rated.

 

The S must stand for slow now

 

HAHA thats what i was beginning to think..
I know the BFG all terrains are Q rated... 98mph?...

 

Man thats bad. In most places at 80mph you're in everybodys way!

 

LOL, thats no lie, cops are usually passing you at that speed!!!
