Hi all, car goes in to ford tomorrow for another go, spent all day on the phone with both ford a various tuners so have a little more info, so far ford have not admitted that there is a fault but they have found that for some reason the vin number on the ecu does not match the car vin

The tuners I have spoken to have said that the boost gauge on the car is controlled by the ecu and is a command not actual boost pressure so although I thought I was making boost it appears I may still have a issue with the boost solenoid. They have also said that if it was a maf or map sensor it would put the mil light on. I was also told that they would detect it if I had a miss or anything else not quite right. They also said that the ecu map was a bit like numbers and that if settings had been changed it would effect everything and recognise it as a fault, which it does not. So now need to resolve the software issue and get them to try a boost solenoid. If not I'm going to take it to one off the tuners and let them have a look at it so fingers crossed.
