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?

They aren’t .....yet

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.

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

    • Its coolant disguised as oil.   TSB 20-NA-166 -  20-NA-166 1..3   "To inspect for this concern, add coolant dye to the system, run the engine through warm up, pressurize the cooling system after warming the engine to operating temperature (let the engine cool overnight) and inspect the suspect cylinder with a borescope for coolant dye evidence. At times it may be necessary to remove the head for inspection. If the head casting line is the concern, the intake port will be wet with a coolant oil mix"
    • Can you sample the pooled liquid, enough to confirm it is oil?   ...That its not fuel or coolant.   Also, make sure combustion gases aren't entering the cooling system.   Simply put, either oil being pushed up past the rings (this really isn't possible), oil leaking past the head gasket, oil leaking past the valve, oil entering through the intake air path. If none of this is likely - it may not be oil.   What could be likely is the fuel injector leaking down. A puddle of gas would still smoke and rough idle. (Same cylinder has the same problem after injector replacement?)   What is the crank time first thing in the morning, when the puddle would be present? Does it seem like the high pressure fuel pump needs an extra second or two to rebuild the pressure that injector 8 may have let bleed off? Check the fuel pressure via a scanner prior to starting the engine.    
    • Good information!  I didn't know about the dementia aspect and asked for a general for my second knee. I'd heard that recovery room time is usually shorter with a general.   The anesthesiologist talked me out of it and I had the spinal.  Inconvenience and/or discomfort is a small price to pay for reduced risk!
    • This is for those over 70 years of age contemplating joint replacement surgery involving general anesthesia. Even some 55 yrs. ago when I took my pharmacology class the dangers of developing dementia in the elderly that had general anesthesia were beginning to be recognized. Over the years there has been some refinement in the cautionary warnings, avoid general anesthesia if possible if you've had close to 10 priors, especially over the age of 70 and/or a family history of dementia. I'm not including the twilight anesthesia induced by propofol often used in cytoscopies or colonscopies. Seriously think about seeing a neurologist and undergo cognitive testing before proceeding if any of those criteria apply to you. Spinal anesthesia may be an option in some cases. I'm in the above camp and although I could use a new right knee, I get fidgety according to a prior orthopedic surgeon when the bone saw spools up or maybe it was the smell of saw blade meeting bone, anyhow I may have one general anesthesia left in me which I will pocket for now and I'm choosing mind over mobility, anyway where did I leave my damn cane!
