Have you tried Triumph's general "high performance" map? When I took my bike in to get a remap for my Trident exhaust the mechanics/techs told me that Triumph's general remap for aftermarket exhausts usually works best.
Now, I don't know if that is true or not but I CAN tell you that it seemed to work pretty well for my bike.
They told me that, on occasion, they'll get a bike in with a Power Commander that doesn't seem to be running optimally. They said that when they take the PC off and use the Triumph remap that the customer always seems more satisfied.
I don't know Jack about remapping and so on... I'm just relaying what they told me. And again, my bike runs great.
