As for the tuner, you'll either feel it or not. If you feel it, it's probably doing something. If you feel nothing, it's probably because the tune is doing nothing.
I fond with JB4 on, my WOT doesn't really change a whole bunch near the top end of tach, but there is definitely more bottom and mid range. Part throttle has changed drastically, it feels like WOT when the tuner is off. My fuel mileage gauge no longer works (don't care), but the economy numbers through the stalk suggest my tuner is doing something. I'm only getting about 14.5mpg with the tuner on, I was never able to go below 19 before no matter how hard I drove.

I have sports suspension so I guess mine has 15mm rear bar.
Below is what they have to say about the power module:
Quote:
Kraftwerk Power Module - $1850 incl GST & Installation
BMW X1 18d
German Made, Performance Plug & Drive module with installation in our shop at Seven Hills. The power module is an external module, so no warranty is in jeopardy.
Our Hi-Tech system contains many smart technical features, and is the result
of many months of design, testing and durability trials.
The Power Module is an external additional control unit. It is internally sealed and cannot be detected by general manufacturers service procedures.
It is also not possible that software updates can disturb the performance of the module. Unlike engine management "chipping" and "flash" upgrades, it never gets overwritten during service enhancements.
