I have just put in a BHZ engine replacing a faulty CDL engine which had failed, the car is mapped by r tech to 370bhp and 380lbs of torque. I have spoken to them regarding a health check/logging and they have said they don't do it unless it's to do with tuning.
So essentially I need to find someone who can do this for me wether it's someone from this forum or VAG specialist. I am based in East London and will travel
