We think we have found the problem!, took it to the tuner and let him have it til he fixed/found the problem.
He replaced FPR got injectors cleaned and serviced ran direct wiring from battery to fuel pump, still the problem was there, last thing it could be was fuel pump, took it out and found the sock was full of black shit!!! replaced the sock with a new one and cleaned out the tank, problem gone! yippee. Thank fark for that. retuned and running great again.
Running a very safe tune at the moment as want to be 100% its fixed so i'll drive it for a few weeks like this and see how it goes. Made 185rwkw so not too shabby, tuner said he can get more but wants to run safe to make sure.
Cheers for the people who tried helping.
