Has anybody come out with a power programmer for a new body style Sierra Denali with the 6.2 ltr. 10 speed transmission?

Gonna have to hurry up and wait. It's going to be awhile before a tuner is out for these. The pcm is locked up pretty good. I was talking with a buddy of mine about it the other day. They can unlock the pcm but there's no tuning support at the moment.

Does anyone know how Hennessey is supercharging 2019 silverados without the ability to program the ECM and tranny?

I asked black bear performance and they said they are still waiting to see if they can but they don't think so, unfortunately.  Hopefully that's not the case.

what about if it's just for the custom trucks ? they seem to be the same engine and trans that was in the 2018 models.

The 5.3 w/6 spd auto can be tuned. 5star tuning is who I recommend.

they are replacing the PCM entirely I suspect. Just like HP tuners does. They may even be using HP tuners PCM

      OBD not ready?

      By davester · Posted

      Different monitors do their test only under conditions specific to that monitor.  you MIGHT find the drive cycle conditions for the monitor that isn't ready on this site: https://lemon-manuals.la/   If it's not there, then it should be on alldata.com for your truck, but it requires a paid subscription.   And you need to know which specific monitor isn't ready.

      from another thread   Update...although the truck sometimes seems to idle weird and the transmission shift a little weird, I've driven about 7,000  miles and no issues.   However, the way GM has handled my rental reimbursement, the situation when my truck quit, and the recall in general has led me to this point...I have driven a GM vehicle for the past 46 years and unless I buy a C3 Corvette, this is the last GM vehicle I will ever own.

      There's some truth to the above, but also, she's selling fullsize trucks and bread/butter CUV's like hotcakes, meanwhile, extracting GM's pickups from the deep discounting sales game.   GM's stock has held its own during her tenure, and the more recent buybacks are delivering cash back to investors and signal confidence in their direction forward. Even with the EV losses.   GM is an example of a modern publicly traded company. The #1 goal of any publicly traded company is to deliver the most value possible to shareholders. Despite being a car company, building the best car isn't GM's path to delivering maximum shareholder value.   McDonalds doesn't make the best burger, or the best coffee.   I've mentioned in another thread, I really don't / won't ever understand Cadillac or Buick in a modern context. Both brands are completely dead to me. I'll cede that the Escalade is a nice SUV, but the brand and nameplate mean nothing to me, and GM will never persuade me to pay north of $170k for a gussied-up Tahoe or Burb. Other people don't mind doing that and that's their purview.   The C8 shares absolutely nothing in common with any other current Chevrolet or Corvette on the market. Since its introduction 8 years ago, it's developed quite the following. It did what other Corvettes couldn't do: reduce the average age of its buyer. GM has something there, and I see them investing in the car. They'd better not mess that up.   We've successfully derailed Grumpy's thread again, but I think this one is meant to be more of a random thought thread so a little wandering is probably OK.

      Sliding doors ftw   Also, Sienna ftw as well.  The in-laws got a 2024-2025 recently when their 2019 sienna was totaled due to a deer back in June.  They've been getting 38-40mpg on the 65mph highway they live on.
