You're probably sensing the computer limiting the speed to the rating of the tires. My old Ford would only do 109, so I spent several hundred dollars on a programmer to fix it. It turned out there was only one tire available from the factory that year with a higher rating, so I only picked up a few mph.

When I got my Edge programmer, I uped the speed cut off and the reading started at 99 mph. I took it up to 130 mph, not that she'll do that.

why push it there? the speedo is there as a reference to how fast it can go, now how fast it should go...

My 08 would cut out at about 95MPH until I used a Bully Dog to raise the limit to the maximum of 135MPH.

 

(I haven't taken it over 105.)

my '06 silverado easily does 100 mph. the speedo goes to 120 somewhere between 2001 and 2006 GM changed the speedos from the 100mph that it had been for decades to 120. Threw me off when i first started driving the '06 b/c on the '01 50 was straight up and down on the gauge now its sixty so i was always speeding. the cops have had their tahoes up to 140-150 from what i've heard

Police Package Tahoe's are limited to 135 MPH They are 2WD as well. No 4WD is going to have a factory set speed limiter above 100 MPH.

Maybe its different for the K-9 tahoes which is what these were if i remember right. plus here in orlando the cops "play dirty" using pretty much any and all vehicles for under cover cars so having a tahoe w/ the limiter off doesn't sound too off :lol:

I have had my truck going 132 mph thanks to an Edge Evolution :lol:

 

Edit: If I remember correctly... truck cut out at around 96 mph stock

Gotten mine to 127 mph with the hypertech. Takes longer to get there though with the bf 285's. Lol

      My brother has an Escalade. The warranty has expired so he told his wife to go to the Valvoline quick lube he uses some times. They told her if her car was a 2020 and newer 6.2 engine they wouldn’t touch it. Hers is a 2019, so they did the oil change.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      The oil filter has NOTHING To do with oil leak. GM sources parts from 1,000's of vendors and as with anything mass produced, flaws are unavoidable.    Putting a larger oil filter will do nothing but satisfy emotions. The OEM filter is designed for the engine and perfectly capable of handling the demands on the engine. Oversize oil filter could result in reduced flow and overall lower oil pressure.

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
