Best of luck with your derv m8, never seen such determination... I salute you. If I may say, I always thought in tuning dervs most important things are not peak horses and torque, but to fine tune it to smooth the delivery of power and make torque curve as long as possible, whilst improving throttle response. Sorry to disappoint you but Vp 30 pumps are rated only 25 kw per cylinder and any forcing to pump more above this figure will have devastating effect to it's reliability... Pushing it's timing to soon may lead to hgf and rev it to hard you will overheat it and it will lead to "Transit" effect until it dies. 180+ hp is more likely to get out of common rail bmw's...
