Range Device or Tuner? opinions please

Picked up my 2015 silverado z71 5.3 crew cab not long ago and im sick of the AFM already. The truck is so sluggish coming out of v4 and does some strange shuddering every once in a while under light acceleration. Has anyone with a 2014 or 2015 used the range device? Or should i get some sort of tuner? A tune is out of the question in my area. I only have 3000 miles and dont want to void my warranty if possible. I wont this truck to be a little more responsive. If anyone of you have tunersm which one did you buy?

I've used the Range device for about 6 months. Works like a charm for killing AFM on a budget and not getting a tune/tuner to void warranty.

I would go with the Range. Especially if you're worried about warranty issues. I haven't personally used it but I've only heard positive things from it.

I'll have my Range for sale in a day or two if interested. I need a full tune since I'm converting to Flex Fuel tomorrow.

you said you dont want to void your warranty so the only real option is the range device

Will a tuner void entire Powertrain warranty? Lets say I do wanna void my warranty, Do you or anyone have any first hand experience with a tuner on the 14, 15 models?

Each time you tune with a tuner, I'm under the impression that it leaves a footprint.

I was considering the $200 Range device to delete the AFM for a while myself. Aside from it supposedly draining the battery after a few days of not driving the vehicle, I've heard good things about them. If you get one, just be sure its loaded with the latest software version. I think it 7.0 or something like that. I've heard some without the latest version had issues. I'm sure there is info on their web site.
