Ordered this today!
Should get it by early next week, it's a DTUK CRD3+ 3 channel tuning system (upgrade chip)
CRD-3 Tri-Channel Common Rail, Boost & RPM Tuning System for advanced driveability
Push Button Map Selection
Up to 40% increase in power and torque (claimed)
Even so, it should get me way over the 230BHP mark with just under 500NM of torque..
The proof is in the pudding, so I will Post about it once it's fitted and set up
