AFM Disabling module question

Just had our motor in our 09 Yukon redone. They say new pistons, ring, valve seals and of course gaskets for oil consumption. Luckily we had 1 month left on our 5yr power train warranty. I'm trying to see if anyone has tried one of these AFM disablers.

It sounds nice but is it worth $200. Any input would be greatly appreciated.

BB will tune it out in person

Bb tune will also tune it out via AutoCal

The only thing that concerns me about a black bear tune is it could void our extended warranty where this is plug and play and leaves no footprint. Am I wrong about black bear tune tune?

You can always return it back to stock tune within minutes when it comes time to get warranty work done

How can you return the BB tune back to factory specs?

I had looked into the Range device. Its an inexpensive option. I had chatted with them. They were pretty nice, they had offered me a money back guarantee if I was not satisfied to.

With the BB Tune AutoCal (hand held device that plugs into your vehicle) you can load tunes on to the vehicle very easily whether it's your stock tune, performance tune, MPG tune or whatever....

That is pretty cool. I had no idea.
Thanks for sharing

I recently picked up the Range Delete module, just before going on a 4,500 mile road trip, and it is great. It is just a plug and forget about it module, goes into the ODB connector. No more 4cyl mode, and if I pull it out, I get 4cyl mode back.

I bought it to help with oil consumption (I will do a brief write up here shortly), and I also found a couple of other benefits, such as:
- throttle response is great now, no more of that weak feeling as the engine struggles to hold speed in 4cyl mode.
- not much, if any difference in fuel economy. Just prior to this I did a 3,000 mile round trip from MI to FL, and got 18.5 mpg avg for the commute there and back parts of the trip (not including running around within the cities,etc.). With the range delete on the 4500 mil e trip (MI to Newfoundland), which included towing a motorcycle on a trailer and lots of big hills out east, got 17.5 mpg for the commute there and back.
- biggest surprise is that I now have engine braking, which I love in the hills. For the FL trip, I didnt have the range delete, and it was just v4 engine braking, there were times I thought I was going to cook the brakes coming down from some of the mountain passes. For the NL trip, with the range delete, great engine braking coming down the mountains. I mean a world of difference.

I know the range delete is not a BB tune, so it doesnt help with more power, etc... but I wasn't looking for that. It does exactly what it advertises, and if that is what you are looking for, I highly recommend.

How much is the range
