Thanks guys, I"ll give it all a try and report back...

DazC, fuel map is all over the place but I have focused on making things more even in the idle and cruise areas, as I said before none of these changes made a difference in the stumble issues.

No verneirs, standard small turbo Escort with T34 turbo, 650cc injectors and RS500 intercooler.
