Has anyone removed the 155 restrictor on their cars? are their firms that do this?

My Z4 3.0 had the restrictor removed as part of the ECU remap, most remaps have this written in to them, however, unless you have an M car there won't be much more to come, when I went to France for the Le Mans 24hr i had the car maxed on a number of ocassions and a top speed of 158 was the max GPS verified my sat nav registered and there was not much left if anything other than a down hill stretch or a following jet stream....

That's not bad for a presumably an earlier Z4 3ltr though. Came across one on the way back from Le Mans in a 993C2 a few years ago and tailed it at *ahem* European speeds for 100kms or so. Beemer was pretty impressive tbh.

When remapped, supposedly around 172mph. I had mine remapped and derestricted, never got the chance to test out the max speed though.
