The kit is 330USD and the dual nozzle upgrade is 25USD. You can go to the online store and put the kit in your shopping cart and get the shipping charges. Normally around 40USD to the UK. You should have a MAP sensor, It will be somewere on the intake manifold or if you have a side mount intercooler it will be on the outlet pipe.
You have a 2.5 bar map sensor on a VW or Audi turbo diesel.
This is the kit you will want. If your going to do dual nozzles use the DO2 and DO3, If single nozzles request for the DO4 and DO5 nozzles.
