A nice power bump for a decent price.

Piggyback.....No way. Just get a proper ECU flash and be done with it.

I see no difference between a generic ECU flash vs a piggyback. Neither is tailored to the vehicle. In fact I would prefer a piggyback as you can remove it, and the signal is altered after it gets logged in the vehicle. And not just that, it will have some residual value as well.

But considering the issues with the GLC in RHD, I'm not even going to consider it for this vehicle. Got to keep it stock.

In the past on other vehicles I've used DTE Systems a lot. Stringent TuV testing as well, I could highly recommend them.

I would wait a while before buying a tune for this car. Motors been out for a while, however the tranny's new. As far as ECU vs Piggyback goes it's like beating a dead horse. They both have heir advantages...personally I prefer a piggyback coming from the BMW community. Easy to install and remove. Less issues with warranty and more difficult to detect from my understanding unless they go in and see how much boost has been used. I could be wrong about the last part but pretty certain they can check that.
