Well, I reset it to 0 today, BIG difference. Still pretty Jerky just off throttle sometimes a little rough rolling off throttle, but definately ridable. Now I feel like it just fine tuning (famous last words) I'm very happy with the result.
Yesterday I spent four hours trying to get guzzidiag to open on pc. Today I used it successfully.
I'd say that call for a drink!
Thanks guys for the help (of course I'm not finished with you lot yet.
