My warranty recently expired on my 2015 Chevy Silverado 1500 5.3L and I was wondering if anyone could recommend a tuner for my year truck. I drive about a 100 miles a day at time and would like to get a little more mpg. I have access to 93 in my area as well.

 

Any help is appreciated.

I doubt he wants to learn to tune it.

 

Probably will want to go with a HyperTech or Diablo Tuner for just a plug in and go tuner.

Yeah that's what I was thinking. I don't really want to have to learn how to tune it. Can anyone recommend one over the other?

I was advised my item had to move to the For Sale section.  Here is a link:

I have the Trifecta Elite tune, I installed it when my truck only had 1,100 miles on it.  I have had no issues and with the Elite tune and they will customize it at your request when you add parts. 

 

The thing I like the most about Trifecta is that you can change the tune on the fly from Sport to Economy by the cruise control button.

So you haven't had any issues with their tune? Have you taken your vehicle in for maintenance at a dealership/shop and did they encounter any trouble with the vehicle due to the tune? I'm only asking because I don't do my own maintenance. 

 

Thank you for your input.

I have had zero issue with my Trifecta tune.  With the Elite tune, they will make changes at your request and so far I have had them change my speedometer to compensate for my larger tires and had them turn on my radiator fans sooner (for towing).  The turn around is like 1 - 2 days (if I remember correctly).

 

I also had the Trifecta Elite tune on my 2015 Canyon for the entire 3 years of ownership, no issues then either.

 

The Trifecta website used to mention what they do to make their tune 'undetectable' (once removed) by not updating some counter or something.  So in the first year of ownership of my Silverado, if/when I needed to take the truck to the dealership, I would simply reinstall the factory tune.  Then once back home, I'd reinstall the Trifecta tune.  The install process takes 15 - 20 minutes.  When I first installed the tune, I would carry my laptop under the rear seat incase the truck died so I could remove the tune before the truck gets towed to the dealership.  Thank goodness, I never had any issues.

I have the FlashPaq F5 tuner. Corrected the tire size for the 35s and the speedo and did a 91+ octane tune.
Made a difference of 11.2 MPG to 12.5 MPG.
There is, also, an 85 octane tune available but I went for the 91+ since I run 93.
Also, it allows for shift point tuning among other items but I left it alone.
I did, however, go with a raised idle at start up (100 RPM) and a raised idle in neutral (also 100 RPM).

I bought mine before the chip shortages, so there may be a wait these days.

Just fyi for anyone that reads this…all this is doing is changing settings in the TCM. Our truck-based OS isn’t capable of altering anything else when you push the tow/haul button. I’ve tried lots of stuff like this (changing driver demand, AFM settings, etc.) with HP tuners and haven’t gotten anywhere. If that can’t do it, a handheld tuner can’t even either.

The Flashpaq F5 alters the ECM and the TCM.
To be fair, one has to purchase the module unlock(s) after getting the tool.
Just like Autosync and BTDiesel with the unlock of the BCM and HMI.

And, @lucas287 , very correct.
However, the post wasn't about the tow/haul button.

i was just referencing changing things on the fly with the tow haul button :) yes, a handheld can absolutely flash the tcm too! Not hating, just don’t want someone to think they’re getting anything other than different tcm settings! (Which happens in stock form anyways when you click the tow haul button haha)

If you want to keep it mild, and by that I mean no plans for forced induction, I would say Diablo i3 would fit the bill nicely. You can add a cai, catback and headers and have Diablew tune for all of the above and get free updates for a year. Would recommend that over Blackbear who from what I understand has a long wait time.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
