how do I get more h power out of my 2017 3500hd 6.0 without voiding the warranty . it has plenty of load capability just lacks on steep grades . any idea's

[Black02Silverado]

To me it is just the nature of a gas engine.  You can install a cat back system and a CAI but that is pretty much about it other than a tune and it would void the warranty.

 

Didn't think one would want a gas engine in a 3500HD.  Most I see are diesels.

Depends on what they're being used for.

In a  2016 CC Dually like mine, the 6.0 gives you  760 pounds of extra legal payload over the same truck with a Duramax . I have a 5000 pound slide in camper so my rig weighs over 13000 pounds and I wanted to stay legal and no regrets going with the 6.0. My 6.0 loaded up can pull over 60 MPH with the camper on going up an 8 % grade, so all the power that I need.

People are always trashing the power of the 6.0 and compared to the amazing torque of the newer diesels, they seem pretty tame.  Old timers like me remember when you went with a big block gas engine to get the highest tow rating . In 1988 I bought a new Ford F-250  with the so called venerable 460, king of the hill in those days. That 460 was a complete dog compared to my 6.0 and used about 40 % more fuel to produce 30 % less power. Gas engines have come a long way. I  loved my 2008 Duramax that I pulled a 33 foot Fiver with and if I ever go back to a big fifth wheel , I will get another Duramax, they are great engines, but for hauling heavy loads, the 6.0 is just fine. 

Towing heavy, you need the diesel.

There is nothing you can do, a tune, exhaust, intake doesn't help.

 

The gains on a 6.0 come from cam, headers, tuning, not worth the hassle, just throw the fuel at it and give it more throttle.

Rvduck, you misread the posts you are referring to.  Somehow the text attributed to me was written by Black02Silverado.  (in the previous post).

 (maybe the new software for the site has a bug?)

 

My post was a response to the Black02Silverado post -  and my response was "Depends on what they're being used for." 

 

FWIW, I'm in complete agreement with you.  Lots of 6.0's out there.  Right tool for the job, etc etc.

 

I just didn't take the time to write examples of those uses.  

Thank you for doing so. 

 

But I'm still confused about being credited for a post I was simply responding to.

No problem,, your original reply was right on the money and inspired me to give my rather long winded reply.  Thanks for your comments.

thanks for all the replies I appreciate all feedback   .Cubfarm

Tuning helps....... they have no ignition timing stock and a bunch of limiters.  Saying it doesn't is just asinine.... unless of course you are clueless tuning then yeah it would not accomplish much.. I am in the middle of tuning my 2017 currently and even with limited advance and removing a bunch of useless stuff the truck runs quite a bit better than it did.  

 

For an ultimate put a supercharger on it.... but then you want warranty so forget it.  I have a VVT cam that would actually work quite well in my truck.... and headers are fairly cheap lol..... but I doubt I will ever do it to this thing.  Maybe... but since I moved up to 34" tires I think jumping from my 3.73's to 4.56's would be quite alright.  The cam in these L96's is pathetically puny and isn't really setup to take advantage of the rectangular port heads..... it's basically the previous LQ4/LQ9 cam with provision for VVT lol.  It's strange that GM made proper duration splits on some rectangle port equipped engines and not on others... but this is so small it's no surprise why it's ground the way it is.

 

If you are all about your warranty don't tune it either....... so at that point leave the truck stock lol.

Tuned via EFI, all limiters removed, 6.0 really doesn't pull much harder, having torque management off helps as does, quickening and firming up the shifts but truck is still a heavy turd.

 

A tune is not going to make a guy love his 6.0 nor is it going to magically pull a trailer much harder.

 

As you said the power is in the cam, once cammed, headered, and tuned the motor will run hard but most don't want to live with the cam or loose warranty.

 

A tune is worth it to me just to clean up the shifts as shift flair and trans tuning is a joke on the 6L90E.

Meh.... maybe your tuner sucks haha lol.  Mine doesn't flare in the first place but then your truck is what.... an 11.. or a 12 or something back when they still couldn't get o-rings in the valve body oriented the right direction.  The tuning on the newest rev isn't that awful stock... mine just shifts firmer now at higher rpm wide open.

 

If yours doesn't pull any harder my condolences I guess.  Even with like 3 degrees of igntion advance wide open the truck runs a lot harder than stock..... Now that I have some octane in the truck it's time to hit it a lot harder.  I see just as shitty of a factory tune on these as the LQ4's had...... and they were night and day with a good tune.  

 

Is it like adding a cam or a blower...... no.... but it's more than enough to notice.  If yours doesn't perform maybe get someone else to look at it.

Did you try using the manual gear shift? I started using mine on steep grades and liked it better.

Holy Batcrap! I had no idea that slide-in campers had gotten that much heavier over the years. Way back in the day I had an 84 Conestoga 9'3" camper that was around 3000 lbs. dry and it was one of the heaviest of that era. It sat on an 84 K20 HD camper special that handled it well except for curvy mountain roads where I wished I had a dually 1 ton like yours.

Some of them are heavy, we were looking at the Alumi-lite brand and they are really low weight compared to others in a similar size and similar amenities.

My old 82 8-ft weighed probably 1k, but it was almost a shell, had a bed, kitchen, and heater...no bathroom, very limited storage, yada, yada, yada.

Some people forget that trucks aren't just for towing. They haul things, too. Of course a Duramax would be effortless with your camper but why spend the $$'s and maintenance for a 5000# weight? To each their own but it's a ridiculous notion that a 3500 has to have a diesel to be useful. In my region you can almost always find civilian a 6.0 dually often in a Denali version. People buy them for a reason. Definitely not the norm but they have a place. I've heard others on here say they'd love their 6.0 with 4.56 gears. To me, that would be the ultimate farm truck. No maintenance and years of abuse built in
