The Real Deal On Custom Tunes

I am a new HD owner and have spoke to a guy at work about Custom Tunes.  I run a Bridge Crane so guys around the job are all about Trucks,  Tunes and more power.

 

A friend of mine there told me about a guy he knows that can get a stock 5.3 or 6.0 100 HP boost with a simple tune... No other mods.  Dyno Tested.   Wondering if anyone here can share their experience with custom tunes they have gotten.  I know there is a very reputable guy here that does custom tunes but from what I read (IF I'M CORRECT) the conversation has mainly been about shift points,  The Tune I have been hearing about at work boost power with no added engine stress and improves MPG's at the same time as the engine is not working as hard to give the same result.  

 

I drive a 2015 Silverado 3500HD

I run premium in my truck (2017 2500hd) and have a good 10 or 11 degrees more ignition advance in the tune along with higher shift points and less torque management tools.  The truck is definitely a lot stronger than the stock tune but that's what happens with better fuel allowing more timing.  I will not dyno because it's a complete waste of my money for something I really don't care about.  

 

The truck is a lot less doggy and pulls a good bit harder in the high rpm range where these engines like to be anyway.  No you will not see 100 hp... that's not happening. Maybe 30 peak at most... if that.  The curve will be cleaner and a lot flatter than stock though without GMs protection system killing power around any transmission shift.  

 

My tune started as one I had written for me but I have changed it enough in my own its mine now lol.

 

As for mileage I notice zero difference and really since the truck shoots for stoich while cruising stock or otherwise it's what you should expect.

Thanks Very much for your thoughts,

 

I am not concerned about MPG's but am about power,  What is the cost of a Tune?  Not familiar at all. The guys at work have the little box on the dash that they can change on the fly....  Not into that I think... LOL...  Just a plug an play would be nice.

Depends what your local tuner charges.  The on the fly and whatnot is mostly the diesel crowd.  You only need one good tune for a gas truck.  I love pulling trailer with mine even with the shifts as firm as they are.  I have hauled about 10000 lbs with the truck and it does really well.  A lot of improvement on mine came after adding 4.56 gears to it.  That ratio should honestly be a factory option on these.  I run a modest 295/60/20 tire and tach around 2100 rpm at 70 mph so its quite drivable.  

 

I own and use HP tuners and efilive.  The handheld stuff like Diablo and whatever else appeal to some but I have no reason to ever switch my tune so it's not something I want in this rig.

 

I do have an Edge Insight Pro I think it's called..  it's a full monitor with the ability to add whatever additional inputs you want over and above the factory obd stuff.  But the nice thing it offers is the ability to load custom HP tuners tunes to it.  I bought it for my 04 Sierra that has a forged 370 with a TVs 2300 blower on it.  I can then in theory have multiple tunes for it if I swap pulley sizes or change fuels.  

 

But on my 2017 that is completely not required haha.

      I could be interested if they axed cylinder deactivation and at least have a button for stop start. I’m sure the HP numbers will be higher. I would want a longer warranty to help build confidence. I’m a less is more guy as I get older. A V-8 work truck model would be my choice. I know a few outfitters for custom additions I prefer.

      2027 GMC Sierra: Official Discussion

      By Zane · Posted

      It's official. GMC pulled the covers off the next-gen 2027 Sierra 1500, and we got the first official look. Full breakdown here: https://www.gm-trucks.com/next-gen-2027-gmc-sierra-1500-v8-trim-changes/   The quick hits: SLE and SLT are dead. The new core retail trim is just called "Elevation". Two new V8s, a 5.7L and a 6.6L built with high-performance Corvette architecture roots. No horsepower or torque numbers yet. The 2.7 TurboMax finally ditches the old gearbox and gets the 10-speed automatic. AT4X moves to larger standard 35-inch tires with front and rear e-lockers, Multimatic DSSV dampers, and heavy-duty Jounce Control Dampers. Over 60 inches of combined display on Denali Ultimate and AT4X, complete with a motorized articulating center screen and an adaptive passenger screen. Seven simplified trims across the entire model line to clean up ordering confusion.   So let's get into it: New 5.7L and 6.6L gas V8s with custom active exhaust tuning and a Corvette connection. Is this the exact engine lineup half-ton traditionalists have been begging for? Purging the iconic SLE and SLT names after all these years to lean entirely on Elevation as the high-volume core. Bold move, or a mistake? That motorized articulating 16.3-inch screen that slides up to reveal a hidden dashboard vault. Awesome mechanical theater, or does it make you nervous about long-term durability? Physically lowering the headlamps in the front fascia to improve road courtesy and stop blinding oncoming traffic. Smart real-world engineering, or does it hurt the truck's aggressive stance? What trim are you putting your name down for on day one? Drop your first impressions below.

      My overnight hospital stay turned into five.  I developed a post operative fever and an erratic  heart rate.  A blood clot in the lungs was the culprit.  This is apparently a common post surgical complication and easily remedied.   I was the youngest in a four bed ward and a Doctor with a Geriatric specialization was in charge of my care.  All of the nurses were good and some were outstanding at dealing with old people.  It was very evident that my age triggered a different level of care!  My advice to any senior going for a hospital stay is to have a trusted family member advocate visible.  If not, you will still be well cared for, but you may discover that your voice  isn't as strong as it once was!
