It appears the torque in the graph is in Nm's, not ftlbs.

nice job though! It's worth the effort. Every time I drive the E91 now, I no longer miss the power of my 330i (well, maybe a little - it's still heavier/slower, but I'm not often racing anyone with the wife and kids in tow).

Yes they are BHP, measured to the crankshaft

I'm pretty impressed considering how the ATs performing our cars vice a 335i!

Deleting error codes is easy - zero the type code and _abc_inc_ factor, its like it never existed.

If they come back you (or your tuner) did it wrong.
