No on top of the intune updater it says not responding so it dont load nothing on the intune

leave it alone.. the intune is updating itself and will reconnect/reboot when it's done.. it can take a while...

Following up with my review. Now that me and the truck has had time to "get used" to the new tune, I found that my shift points were all screwy (as posted in the Throttle Boost Issues post). Short shifting, clunky 1-2 shifts, and bogging after the 2-3 shift at light throttle was making me nuts.

So, I turned throttle boost off and returned the TCM to stock and all is much better now. The truck is still way better than stock with the just the canned 87 octane tune.

Point is, ignore what I said in the OP about 15% throttle boost. It really did seem to make the truck much more lively, but it has undesired consequences.

Throttle Boost is sort of like medication that the doctor prescribes. It may work great to fix the problem, but also causes side effects...

Ahhhh. If there were only a way to have my cake and eat it too...

So does the trinity and the intune fix the stabilitrac issues?

[06MonteSS]

what stabilitrac issues? there is nothing in the tune files for stabilitrac.. the programmers do not and can not change anything for stabilitrac...

Not being able to fully turn off stabilitrac is going to get me stuck. (even when turned off comes back on at 56 km) Was hoping that there was a fix for this.

[06MonteSS]

nope.. only way to disable it is to hold the button on your dash.. that's it..

stabilitrak is not a function of the ECM or TCM, so there is nothing that can be done with it with the programmer.. this is not a programmer issue...
