My problem has been solved though it's hard to tell what the cause was due to so many parts being changed in the build..

My guess is either the TPS or bad earthing (battery inparticular). I now have the battery relocated to the boot with a solid earth...

Point to note is i also run a different ecu now... Link instead of Apexi
