Unite Fuel Injections (WA) are very helpful over the phone also John, I never had to put my vehicle in with them but at one stage someone was trying to get me to fit a new turbo and based on the year/model and performance they told me I didn't need it and just to get it serviced (they don't do servicing in general, just things specific to fuel injection).   Did that and it solved the problem
