Yes, that would be it.
It will only include harness, tune box, manuals, zip ties, and alan wrench to open the box and adjust the dial.
There are no display.
To switch the tunes on RC Ultimate is by opening the box and change the dial, while BMS Stage 1, you need to use the sold separately BMS DATA USB Cable.
If you are talking about switching it on and off, there is always on mode.
The one that you can switch on/off, change map, etc, that would be the BMS JB4 Stage 2.

I'm a bit confused, your website says the jb4 stage 2 is not compatible with the X5 DME. Is this incorrect?
Also does the jb4 stage2 require tapping wires in the DME with wire splicing, posi-taps, etc...?
Unlike RC or BMS stg1 which plug into the vehicle using OEM connectors.

Yes, those info are copy paste from their website.
I am not sure about E70 DME, but it is compatible with F15 DME.
JB4 Stage 2 require a use of posi-tab to connect to the CAN BUS. But, they just released the new addition where you can use the OBD2 port where you can buy it separately or make it yourself.
It still used the OEM connectors for the Fuel Rail, TMAP, and MAP sensors.

Are we able to run the RaceChip Ultimate on a stock F16 X6? or Do I need upgraded intercooler and what not

It looks like RC Ultimate would be the best tune as far as convenience and ease of use.

Yes, you can run RaceChip Ultimate or BMS Stage 1 on a stock F15 X5 / F16 X6. No intercooler upgrade needed.
But, I do suggest to upgrade the chargepipe as it is known to break even under stock condition. It will also increase the throttle response, especially under hot condition where the plastic pipe become softer.

Gotcha, thanks for the feedback. Got some decisions to make once my F16 is here next week

Yes, BMW put a cover on them now. Mine is early built 2014 F15, so it was bare like that.

This is what i was looking for

Im returning my f10 lease that has the jb4 stage 2 and bms intake and seems i will be able to use both in my f15

Question: did you try using map5? Supposedly it autotunes with a higher psi based on current conditions.

Thanks

Yea, but don't like it.
The map 2 is my liking.
