This is the (im)famous Startech SD6 upgrade that has had (especially) the British CRD owners chomping on the bit.
The kit has been available for quite a while now (about 6 months) and I am led to believe that its performance improvements are very impressive - which must be very spectacular as the standard CRD couldn't be described as a slouch.
The good news about this tuning kit compared to others, is that it has been developed by Startech, a division of Brabus, a division of DC and so when it is approved by individual countries the 3 year DC warranty will stay intact. I understand that it is already approved in europe and I'm just waiting for DC UK to give it the nod.
To put the upgrade into context, once fitted a CRD will have more torque/sheer grunt than a Hemi, and all from as low down as 1600 rpm - it should be good fun if it gets approved for us Brits in the UK.
This
upgrade which is available for £249.99 ($460) will boost your torque/sheer grunt upto 660 nm - and totally invalidate your warranty !!
All the fun of owning a diesel burner.

p.s. I contacted my insurer who would NOT be looking for a premium increas if I had Arnie chipped - as long as I kept underneath the 340 bhp of a HEMI, the torque figures never counted for them.
