    Thanks.I do have xdf that has the patches available. I just haven't had the time to fully read all the things the xdf I have doesn't. Been wanting to use the newest xdf but the names of some things being different from one to the other xdf kinda confused me.after checking location to verify it's the same setting I'm playing with I figure I should take the time to verify each item so I understand just what I change.the bpw I have left alone at 144 last 4 logs and been raising injector bias.went from .45 and now at .49.. and that's gotten it better so far than raising bpw.had been up to 153.but 144 is what the calculator comes up with.thanks for the help.it's very much. appreciated.
