I have a 5.3L 6 speed Silverado.  I installed the Diablosport preset 87 Octane ECM Tune and the Firm Shift TCM tune.  The truck has more consistent pep now with smoother, firmer shifts.  A couple months ago I was considering trading up to an 8 speed thinking more shifts might be smoother.  Am glad I did this instead.  Can hardly wait to get my DiabLew custom tune done in a few weeks. 
 
Bear in mind that unless something changed recently I don't think the 8 speed transmission can be tuned yet...


I believe it can be tuned now. I love the 8 speed transmission. I was hesitant at first for sure. It always finds the powerband.

I believe you have to send off your TCM to be unlocked and then it can be tuned. @1SLOW1500 can probably confirm or at least update this belief.

Just gloss black but can be color matched.

If I have color matched caps already,  will the caps fit these mirrors?

.. been testing this "mod" for a while now and it works great. Absolutely cannot justify the $14.99/mo CDN for the onstar/mychevrolet app to extend your keyfob functions to your phone to remote lock/unlock, start your truck (unless you were lucky and got your truck before the policy change).. so found a Free app on the Google play store called GMRC that does this via a compatible OBDII scanner (I use OBDLink MX) and a slave cell phone.. free, no monthly fees.. simple, leave your/spouse cell in the truck then the app sends a sms text code that the app identifies and presto.. unlock the door, start the truck etc.

Seems kinda worthless if you have to leave your phone in the truck. Or did I miss something?

Not sure. I am removing my driver side mirror and will tear it apart. At first glass, I think it would.

I had excessive vibration on the glass and hearing a clicking sound during fold operations. So the manufacture is sending me another one. So I’ll have the opportunity to tear this one apart.

There just isn't any other way to say this...Phil you have one bada$$ truck right there!

Thanks! Appreciate the kind words! Worked hard to get it where it is at... paying attention to the little details too. Learning, sharing, and always changing.

I guess you cannot connect with crisp gm customs unless you are on facebook? No website?

Yes they are able to tune the 8SPEED. Some need to be mailed in to be unlocked. But worth it.

Is there a certain set of VIN numbers that tell you if you have to send it in or something similar?

I think it’s more the year...all 2018 Sierra/Silverado 1500 series 8 speeds have to have the TCM sent off for unlock, I believe the 2017 too but I’m not sure on that. Someone @1SLOW1500 knows way more than I do on this subject but so do a lot of others so hopefully they can chime in but if you have a 2018 then yes you have to send it off.

***just checked your profile and you list a 2018 so yep, gotta send it off***

    • I’m definitely interested to hear the end result here. 
    • 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.
    • 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. 
    • 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.
