Thanks for your help,
Does it need the 200 Bar Rail Sensor ? I was on two minds about fitting that sensor but I just followed the Conversion guide on R Techs site, ill get onto the tuner later today an say that to him I have the old sensor in the boot luckily

Some tuners say no, some say yes. I don't see why you would need it personally as the K03 sensor is 140 bar iirc, which is still 5 bar higher than the RS4 relief valve.
The tuner I use has mapped quite a few K04 conversions and didn't need or use a 200 bar sensor. He has also done one with a 200 bar sensor where the customer had already fitted it, but it was just a simple case of telling the ECU it's using that sensor :happy2:

Yeah I thought the same but as you say I'd say it just tuners preference id say both are capable
