    Hey mate cheers for that it has worked, admittedly I did forget to set the fail on first error, but have never had to set the other things you mentioned. In saying that I wonder would running a sd custom opp masked the issue and this one is a standard os. Anyway cheers for the help I believe you have help me a few times over the years and I do really appreciate it.

    Dam I jumped the gun it has done it again. I think I might re-tune it on a custom os.

    maby try disabling the cat test also, when SD u should change the max fail 60 to 200 also for the throttle body, if u download the newest beta there are some more torque management settings related to spark and throttle could be worth a check
