Inconsistant Throttle Response

This is probably the TQ management or the transmission not knowing what gear to pick but I was wondering if anyone else is seeing this...

If you're just coasting or rolling into the throttle alittle maybe to merge into traffic or to pass someone, sometimes the truck takes off like a scalded A$$, othertimes it just sits there and slowly comes up to speed. Being so damn quiet its hard to tell without looking what gear its in or what exactly is going on.

Am I alone here? its annoying! Will a tune fix this? I've got the latest calibration from ford.

Sounds like sometimes you hit the transmission at the bottom of a gear wih the converter locked up and it's bogging down and sometimes your catching it at the top end of the gear and its able to accelerate easily. Solution? Push the pedal down farther and force it to drop a gear.

I am not sure if this is exactly what you guys are talking about but I am getting more frequently that when I am pulling out somewhere and easing into the throttle that the truck bucks and stumbles for a second or 2 then takes off. Sometimes it is a hard stumble and sometime just a slight one but either way its annoying. Guess it is time to make an appointment but I already know what the answer will be... can NOT dublicate customer complaint!!

So funny story, my dad has a 2011 tahoe and it too has the torque mgt. He has been complaining about it to Chevy/GM and so they let him take a tech on a ride along with a computer to see the issue. Everything we have heard is true. It is to protect the tranny so it will last past the warranty. He said they have numerous customer complaining about it but ford, dogde and chevy all do the same thing and all we can do is complain as there is no fix.

He asked him about toning the TM down a bit, but not completely off and the tech said they can tell that something change and will void your warranty.

He also said that the trucks are so leaned out to get the best mileage just as a side note.
