I have a hypertech max energy tuner I will use to program it soon after I get a full tank of e85.  I will then have a good baseline tune I can play with to try and get more power.

I'm interested in doing this although I'm sure warranty issues could arise. Thanks for your hard work for providing the information.

If you program with the Hypertech are you able to use the HP tuner to see what changes was made??

Yes, sir that is my plan!

That is why I am using OEM parts, I doubt they will know, its very subtle. I have 31000 miles on my truck now.  This was a $100 option on my truck, so its not like it is not supported.

Very true only way they could know is the RPO codes which they never look at it. Hmmm. I may have to wait till you take your truck in for service and see if they say anything lol.

I'm trying to figure out how to make a new RPO code sticker for my glove box. :)

I tried to see what is involved in the changing the fuel line, and those retaining clips are a pain...so I am going to just replace all of them, it's only like 20 bucks for new clips and I don't want to waste time babying them.

 

I also bought extremely long needle nose pliers from Harbor Freight for $10 to open up the metal retaining clip on top of the trans, I want to attempt to do it without having to unbolt the cross member and dropping the motor/trans.

I wish our 2016 Suburban had the E85 pigtail.  No such luck.  I would like to convert it.

Here is a company that makes reproduction labels, I just photoshopped  it to change FH0 to FHS.  Label is kind of expensive.

My 18 doesn't have rpo code sticker.  It has the bar code scanner box.  That shows all the codes when you scan it.

Have you tried a QR code reader on your smartphone just to see what it says yet?

Dump the text, edit the FH0 to FHS then recompile the QR code https://www.the-qrcode-generator.com/ 

 

Take a screen shot of the new QR code and a picture of existing label, photoshop the new QR code on the existing label, send to the printer to have the label printed.

Well I am at 60% Alcohol now so I tuned It with my Hypertech Max Energy 2.0 using the following params:

Premium Fuel tuning

Throttle Response - Track

Shift Response - Track

Shift Firmness - Street

 

I tried a couple firmness settings, and the heavy acceleration shifts were way to harsh for me so I have been dialing it back,  The more aggressive shift firmness had great part throttle shifts but very clunky high rpm shifts.

 

I pulled HPtuner dumps after each one so I can figure out a good medium.

    • Follows the motif on the Sierra EV.  Satin finsh to the lower bumper area, painted above:   Elevation       Denali      
    • Not exactly what I was hoping for, but I do like it. I wonder if they'll bring back Smokey Quartz Metallic? 🤔 https://gmauthority.com/blog/2026/06/here-is-the-all-new-2027-gmc-sierra-1500/
    • Whoever greenlighted the work truck matte black front bumpers on every trim but the AT4X should be fired!  I was hoping that was an AI mistake, but just realized they were on every model of the 2027 Silverado too.     Some parts of the interior do look premium, but the Denali Ultimate dashboard looks like an afterthought.  At least they appear to have lost the microfiber the high end Silverado models showed, but the '27 High Country dash looks better than the Denali.  
    • New member here. I am researching a read-first event-recorder concept for late-model GM V8 trucks. This is not a sales post. There is no product link, price, preorder, or mailing list. I am trying to determine whether the underlying problem is real before building anything.   Has your truck ever had a brief problem such as: - rough running or a momentary misfire - an oil-pressure warning or unusual pressure event - reduced power or a brief stall - a U-code or lost-communication problem - a symptom that disappeared before the dealer or independent shop could reproduce it   If so, I would appreciate the following details: - year, model, engine, and mileage - what happened and under what conditions - whether a DTC and useful freeze-frame data were stored - whether the shop was able to reproduce it - what the eventual confirmed repair was, if known - what additional information would have helped the diagnosis   The concept being evaluated is a removable leave-in recorder that continuously retains a rolling window from before and after an event. It would not tune, reflash, clear codes, or change the vehicle calibration.   I am also not claiming that it could predict lifter failure or see every internal ECM variable.   The real question is whether continuous event history would add enough useful evidence beyond freeze frame, GDS2, and existing scan tools — or whether it would simply be another unnecessary gadget.   For owners and technicians, which problem would make something like this genuinely useful: 1. intermittent misfire or AFM/DFM-related behavior 2. oil-pressure events 3. lost communication or electrical faults 4. none of the above Please be blunt. Negative feedback is just as useful as positive feedback.
    • No tears over the SLE and SLT trim levels disappearing but I kind of loathe the "Elevation" name. It's a truck--skip the elegance.   The slab-dashboard design is decidedly different. Almost has a Hummer flavor to it. "Professional Grade" seems to be leaning very white-collar, tech-driven these days moreso than blue-collar, functional design.   The Silverado would be my choice between the two new trucks. Pleased with the engine lineup in both. The GMC is a little "too much" for a truck, IMO, and the Denali borders on ridiculous - but I do know there are buyers for luxury trucks out there. It's just not my speed.
