E91 been remapped torque limit? RR data inside..

Right after a bit of advice as ive recently purchased an e91 335d. I found it a bit tame coming from a stage 2 edition 30 so decided to remap after reading a lot of good stuff on the forums.

Im working in south wales so found a place down here and decided i wanted them to do it.

Basically they found the ecu already had a custom file which was dissapointing but we decided to take it on the RR to see the numbers and maybe they could add to it.

The numbers were 304bhp and 512 lb/ft @ the fly (roughly after converting whp to bhp)

They then added there custom map to my car and the numbers were 270 bhp @ the wheels and 512lb/ft!
Think this equates to somewhere around 600lb/ft engine torque which is well past the 700nm which zf qoute the limit is on the box.

Here is the data and curves.




What do you make of it?
Thanks in advance.
