thank you!  this makes perfect sense... and if i strip this down to an over simplified manner, it sounds like i can get slightly better gas mileage (or at least not worse) with some sort of better performance...without sacrificing reliability...this helps for sure!

Your welcome. I think you see it for what it is. Eyes wide open then. Have fun and check in and let us know how it goes.

Back in the day we would add a shift kit to the transmission to increase performance and lengthen life. One of the reasons they don’t do that at the factory is most people would complain about the bump out of the transmission. We would advance the distributor (timing) to increase performance. We didn’t have to worry about top end or shift points and V-4-8 didn’t have that. Basic hand held tuners do that, they add a little feel and drivability to your ride. There’re pretty harmless. Custom tuning is where you can fine trouble, research is recommended. I found it worth it to me, I’m not in the habit of repeating mistakes. I been around long enough to use banks, gear venders, Vortec, Whipple, MSD, etc. In the 100-150K miles I generally drive my rides non of those mods or tweaks has lead to failures, just fun.

I can't speak directly to tuning the newer Ecotec engines, however I will say that in my 2008 Silverado with the 5.3 Vortec I had a Bully Dog tune on it and it was fun, it certainly unleashed a little more torque and made it more fun to drive. With that being said I currently own a 2014 Camaro 2SS with the 6.2L LS3, modified pretty heavily, headers, exhaust, throttle body, cam, etc. and on this wonderful GM vehicle that was untouched until around 5k miles ago I very recently had tuned to make the most out of the mods. It was worth every dollar of the $1200 I spent to have it professionally tuned on the Dyno and with people who knew what they were doing, some would call them professionals. I will soon be throwing a tune on my 5.3 Ecotec for sure, my last GMC had the 6.2 and had more than enough power so I didn't even bother with it. Let me know what you go with and what you think about it, all in all though I say TUNE AWAY! 

 

Happy driving!

I went with the Hypertech  Max Energy 2.0 mainly to turn off afm. I also set the throttle response to tow mode a 25% increase. I have had no more clucking or kicks in the ass or searching for gears in the trans. Fuel mileage my be down about 1/2 mile per gal.  I hated the afm form day one and got tired of driving in manual mode all the time. I'm happy with the performance of the engine and trans now.

I'm a rather conservative driver, and want/expect my vehicles to last for >150k miles.  This is my first truck (2017 5.3 4x4), but am surprised and worried about that same transmission "searching" and clunks that make me thing I'm wearing down what SHOULD be a smooth tranny.   It's basically the same in the 3 Sierra's I drove before buying, and in 2 more after.  I guess I was hoping it would work or "learn" it's way out, or I'd figure out how to avoid it, but it just concerns me every time I drive around town (1st --> 2nd --> 3rd and then back down are the real culprits). 

So......if ANY kind of a tune makes the tranny work SMOOTHER, then I'm all in, cost be damned.  I want a comfortable, smooth ride that at least gives me the impression it's going to last a long time.

 

Any other "conservative" drivers out there have this same positive experience southern_sierra has had post-tune???

Thanks Spenpet!  That thread's issue seems VERY similar and related for sure, even if most (if not all) of those reprograms were for the 8sp and I (and others) have the 6sp tranny. 

I'll prob chime in on that thread since the subject line is more appropriate than this one...

sorry I don't have a better answer, i can only speculate that you might have a similar experience if the dealer reprograms...

If you do any modification whatsoever to your vehicle bigger tires gear change cold air intake Mufflers it's a must to get a tune otherwise your vehicle will not run properly and the speedo will be off. I run a trinity Diablo sport 1000 and it changed the whole way the truck acted I would never go back to stock.

An intake and muffler change don't require tuning. Been custom tuning vehicles for nearly 10 years with HP Tuners just for reference.

 

Larger tires is a good idea and a gear change is a must for tuning.

I just got a refurbished Diablo intune i3 on e-bay, for about $160 less than new. Loaded the 87 octane tune (you can keep stock tune and change other parameters like AFM etc), turned off DOD/AFM, increased throttle sensitivity 10%, firm shift trans tune. It did what I wanted it to do. I have absolutely HATED the AFM since day 1. I've been driving in M5 for over a year to avoid switching to 4 cylinder mode. I have my 6 speed trans back! I'm still considering a custom tune from DiabLew for driveability improvements. I too, do not want a race truck, just something that I enjoy driving. I'm getting close.

very happy with my tune from blackbear. 

truck runs and drives like it should. holds gears longer, no lugging around corners, stop light to stop light shifting 4 gears etc. it drives like a truck should. 

i run it on 93 all the time, regardless of the tune, it has 11:1 compression, and i didnt want any ****** on timing even with the stock tune. 

the tcm tune is spectacular in everyway. 

you dont need to hot rod around or have to hot rod around to have a tune. a tune can give you more power yea. but the drivability is what is really noticed. 

a tune is worth it in every way.

 

when i had mine tuned, i told them what i wanted, a good all around 93 tune and their popular and reliable tcm tune. i didnt say i wanted to burn tire, race, etc.  i dont drive like that. but i can tell you, it does burn tire way better and get up and go 10x better.

      Missing thrust bearing? And oil selection

      By Black02Silverado · Posted

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By revmanii · Posted

      So, lot's of googling and reading, and a trial fit found, that indeed they hit the newer fatter caliper. I did some re-testing today, and found just 3/16" worth of washers was enough for the wheel to spin freely. I added 2 more on each, and again it spun freely. Tested lock to lock with the 4 washers, about 5/16" not quite the 3/8" Im considering, but pretty close. No issues. I've been looking at the BORA .375" spacers and using extended lugnuts to get back lost thread due to the spacer. All the ET lugs I've seen are all .33" reach inside the wheel lug holes. For those that don't like spacers or think they're unsafe, I think it depends on what type of spacers you're using and making sure you get good quality hubcentric ones, and if you're using bolt on ones, regular mainenance, checking the spacer lugs. Not wanting or needing that much spread. Looking for the minimum that will let me run these rims and tires.  it does look to stick out a little, but I really want put these on. and use the stock all-terrains in the winter.
