The 6.2 has alot of balls but down low its def lacking I feel

Im looking to get alittle more low end grunt and just some more all around power, especially for towing.

Would a cold air intake be worth the money?

What else could be done? I kno a tune, but black bear doesnt seem to be in my area. NY

Are there other tunes/chips/programmers that would be worth the $$$$

 

Anything else, please feel free to learn me :(

Thanks

Check out the Diablo handheld tuner.

They are trying to get enough to have another tune in NY. You missed out on two tunes in the NY, NJ area this year.

 

You can also do a cable tune by mail with Black Bear.

 

I just recently purchased this truck, maybe 2 months ago.

Im still new to this, Just recently heard about the tune

 

I would consider the cable tune with Justin, before I would totally rule out getting a BB tune

 

what is the difference in the cable tune and the live tune performance wish

what are the pros and cons of the 2

With a cable tune you'll get pretty close to what you want. Many times it'll be be spot on. You may need to tweak it a bit after you drive with the new tune. With the live tune you'll get it exactly the way you want it right then and there. Many people have done cable tunes and are more than pleased. Re-tunes are free, so you can have it adjusted whenever you want.

This is correct for the most part. Remember for the Denali the only way the transmission can be tuned is with a live tune. I highly suggest getting a Black Bear tune and if at all possible do a live tune. A cable tune is the next best thing.

My tranny probably isn't much of a fan, but I love the wheel spin during the 1-2 shift after my BB tune. :jester:

 

I think you're right about not having much torque right off-idle. I could spin the tires off-idle in my heavy 4x4 KR F150 but it would fall on its face after 15-20mph. This truck seems to pull much harder as the RPMs climb. And having Justin raise the shift points so that they happen after peak HP improves it even more.

 

But that's just the all out performance benefits. He also changes things so it doesn't want to get to sixth gear as quickly and partial throttle acceleration is also improved b/c the transmission kicks down to a lower gear with less throttle input.

 

Anything over 3/4 throttle shifting does feel pretty aggressive. But I find I don't have to go that far anymore to get good acceleration.

What kind of dyno is he using? Justin was teaching up in Albany at a shop, forget the name though, I know his name was Howard :jester: .

 

We also have a shop that is selling our tunes in Long Island, NY....

don t know what dyno he uses. He is 1 1/2 hrs north of Albany. His name is Jim. I have no stake in his shop but if someone this far north is looking it can be tough to find. I don t want to advertize here as I know we have supporting vendors. But if someones local I ll point them to him as he s done good work for me twice.

      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.
