Steinbauer tuning box taken off my 330xd.

These claim to take power up from 254bhp to 303bhp. While I do not have any dyno output, the difference is huge.

Also comes with a wireless remote so you can turn the box on or off on the fly.

For those who don't know much about these - they're essentially the same as the ACS tuning boxes (~£2k) and unlike other boxes these alter individual injector timings instead of increasing the fuel pressure.

Are they easy to fit & what’s the wiring situation like once fitted?

Are they tucked away neatly?

I have instructions.

It's ever so slightly fiddly to get to the 6th injector but easy.

All hidden away afterwards!!

Can vouch for these, had one on my F31 330d, did a good 30k miles with it and never had an issue. If you didn't know it was fitted you would never spot it.

Does not change the character of the performance just gives it loads more of what it has, a worthwhile addition in my book. GLWTS.
