I'm not one to change a good thing. I have been driving GMC since 1989 and am quite happy. But times change, and technology advances.

 

My question is.....

 

Does anyone have experience with engine programmers, ei Edge Products? And have you seen any improvement in mileage and(or) towing. These plug and play products look interesting but I am not sure I believe the claims of increases in horsepower and mileage. Any insight would be appreciated. I should note I am also looking at aftermarket exhaust systems looking for the same kind of performance upgrades. I don't mind a bit of rumble, but I am afraid of the noise on the highway as I spend alot of time there.

 

Cheers!

I had Edge it was ok. I averaged maybe 0.5 mpg more with it. The best part is the gauges and if you get a programmer I would get one with display like edge or the new Diablo.

 

Like everyone else I got a Blackbear tune now and love it. Mileage is better than edge, but its too cold to judge right now. And dont expect to gain lots of mpg, an exhaust doesnt help much and sometimes hurts it, cold air kits wont help a lot either. Tunes help but only 1 to 2 miles.

I've been very happy with my diablo and what it's done for the truck. Once dialed in, it makes the power band stronger and smoother, and removes 80% if not better the horrible throttle delay. As far as mileage increase, I can't say I personally saw any. If you don't care about TQ management, then Diablo's one of the best choices as far as I'm concerned for many reasons.

 

You can update them when newer improved software comes out via computer, they have their own forum for support and tuning suggestions, they can upload custom tunes from a variety of venders, and they work.

 

With that said, My diablo is going to be for sale in April. I'm getting a blackbear custom tune because I want more.. :D My main interest is removing most of if not all of the torque management and tuning of the transmission. Something the Diablo can't perform on the GMT-900 trucks yet.

 

As far as exhaust, if your doing it for mileage, your going to be disappointed. If you want it for a muscle car sound, then :) Corsa, Borla and Magnaflow make the best in my eye. They are all stainless steel and have a good reputation. My favorite being Corsa simply because there is NO drone at all.

 

Good luck

I just got a Superchips Flashpaq a few weeks ago, I've been running their 91 Octane performance tune and what a difference it has made in throttle response, no delay, no AFM, quicker firmer shifts, etc....

 

My fuel light came on, so I fill my tank with 87 Octane and uploaded their Mileage XS tune to the truck; I will post what my mileage gains are after this tank has ran... :)

      The Peckish Synapse

      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.
