i have not touched the timing but i did realise there was a fuse for heated seats missing. I have put that back in and the cold start injector is still disconnected and now it starts and idles stronger and higher.

Can't believe a fuse could be tha cause.

My final test will be from stone cold i guess in the morning. I'll report back an i think it is the blow in the exhaust being the problem. When on boost u can hear the air escaping from the gap in the turbo and the loud farty sound gets louder as the exhaus is blowing

cheers folks appreciate all the help chaps
