Cheers for the replies guys, finally managed to get it sorted at like 10 at night! The settings we had on the ECU were always right it was the existing car wiring causing us issues, a previous owner must of had a piggyback ECU in the past and wired it in badly. Out mapping guys wouldn't give up and went through the complete wiring to find what the hell was going on.
Got it going and they put a base map in but now looks like we've got an issue with the turbo as when they asked us to out our foot down whilst starting to map it they noticed it would smoke heavily when booted and there was oil in the smoke. It's has new stem seals, head and the compression was fine last time we checked.
Cheers again though!
