My 17 is running 91 tune from BBP. Flashed the ECM and TCM earlier today.

problem with that is your dealership is going to know it for warrantee work and if they flash it back to stock your going to have to pay again. If something like your tranny gives up the ghost and they have proof shift points or pressures have been changed your going to be out of luck. I don't even care to put a tune in mine. I come from the 70s and the hp on these new trucks is really plenty good for me. What I want is to be able to change tire size, gearing, and maybe deactivate the 4 cyl cut out. Even that isn't a game changer. Like I said even something the aev unit for jeeps would work fine for me.

Last time I spoke with Jared, they still can not flash the TCM on the 2017 8spd?

Just for an update. I spoke with diablosport and they said to check back in with them in a month for support for the 2017 trucks.

yes, GM changed their ecm/tcm programming and encryption.. and when support is available, it will only be for the ECM/engine tuning.. no tcm/tranny tuning on the 2017's.. unfortunately the only solution for actually tuning tcm correctly that they have seen, requires removing the tcm from the truck and sending it out to be modified/unlocked for some fee, then reinstalling it and paying for additional credits to tune it. If there's a way to do it without removing the tcm, they say they'll find it.. So, as mentioned, when any support at all is finally available, the 2017 support will only be for the ECM/engine tuning.

We have a few tuners that currently can flash both ECU and TCM for the 2017 6.2L 8spd beasts, but like mentioned above you need to remove it from truck send it to them and they will update and send back.

I spoke with with a very reputable tuner that should be releasing sometime 2nd QTR and offering that will allow us the cable connected to laptop and flash both. They are not ready to release yet to the public, but are very close.

So to avoid confusion, when I see no TCM support without removal and all that jazz, is that ONLY for the 8 speed, or for the 6 speed as well?
