Took my car to a company called hypertune today, Shane had a good look over it and found that the vacuum pipe on the actuator was on the turbo and vice versa. I think that's what he said.
Anyway took it out for a drive and it was a lot better at first but at higher revs it really started stuttering.
So Shane put it on the dyno and data logged with my stage 2 map, standard map and their own stage 3 map. He found it is under power on all maps, but on the tuned maps the fuel rail pressure drops a lot without throwing up an error code for some reason. Not sure why it's not doing it on the standard map tho
