You specified software so I would have to recomend hptuners.com. It will do any type of tuning and is overkill for just changing the speed limiter.

None of the handhelds can match software for tuning but any of the handhelds can change speed limiters and are easyer and cheaper to use.

Like the other options - maybe overkill for just the speed limiter, but the Hypertech will do that as well as some other tuning, including correcting the speedo for oversize tires. I wasn't that impressed with the tuning changes it made.

hptuners doesn't have software for the old body style trucks.

Sorry didn't pick up on it being OBS.

How about LS1 edit than?? I think that is what Westers was using on the OBS trucks.

i was thinking about LS1 edit. but i dont know whats the compatability. but i am looking to further tune the truck a bit later so thas y i wanted something simular to my Lt1 edit software. so if LS1 edit will work on a 99 Tahoe LS 4x4 with a 350Vortech in it then i will use it...

LS1 edit is only for the GEN III engines (LS1, LS6, 5.3L, 4.8L, 6.0L). Hence the name "LS1" edit.

according to carputing the LS1 edit is compatable with the 97-05 chevy cars and trucks and the L31 is included in the list but i sent them an email to find out...

      The Peckish Synapse

      By Grumpy Bear · Posted

      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.
