Race Chip Piggyback.. anyone have one?
Just purchased the Race Chip with Mid pipe and wondering if anyone has any experience with it. I would have loved to do a proper tune, but pulling the ECU for a bench flash then sending the ECU to Russia and then having to do it all over again if the dealer over writes it is not for me.
So, for now its a race chip. Anyone with one care to share some opinions?

Oh, I have a 2022 X4M competition BTW
