sure, yes in the UK, went to BW chiptune in Hayes. Sterling job, still very smooth and boy does it pick up quick and fly.
I tried a DTUK box for a while, had a few issues of going into limp mode, it was mainly so I could remove it for dealer servicing. It became a pain when the N57 put one of its plug in point at the back if the engine near the bulkhead.
Jason at BW really knows what he's doing with BMW's after a lot of research and recommendations i chose him and have not been disappointed. Absolutely no issues so far. I'll post some 0-60s etc. bit later but expecting very close to 4secs...
