ECU chip for the 35d
 

Given that the new 35d is TT and easily modable, does anyone know if there's a chip available or something in the works?

there's been several available for the pre-adblue version for at least a year or so, if you google '3.0sd performance chip' it turns up a few. not sure if they are compatible with the US version but it shouldn't be hard to find out

Try DMS Automotive Porsche BMW Mercedes Performance tuning they are one of the most established firms in the UK and also supply in the US. Their tuned cars have been reviewed several times in BMW Car magazine among others.

It's possible to get plenty mroe than 50 bhp extra but I think that is all anyone sensible will increase the power by. Beyond that and the strain starts to show elsewhere.

I've had mine done by DMS. Not cheap but the result is brilliant!
