Hi,
Not getting on with this as well as first thought.
I done a 307 3 times till it would stop throwing up a turbo over boost fault, also used my diagnostics foc to cure fault.
Had a Kia 2.5 td which when customer took it a way phoned me up and complained at bad flat spots! Going to have to put it back to normal. Will persevere but many more problems and it will be up for sale !
Just like to add the guy's at BHP UK are excellent and sort all issues out !
