    Gav,

    Full flash (and two step) no longer required, just make the amendments and then cal flash in the changes. Until you get happy/confidence do the cal flash then trundle along gently to check the log before venturing into aggressive throttle/high map areas.

    Cheers

    Anything below 40kPa will be ok, yes 15kPa is stock.

    +1 what Jim said, do cal flash from now on.
