What I would do and Christopher will probably back this up would be to get rid of the gems controller and run a bridge controller from pyschosled. If you buy it run it for awhile and you'll see what I'm talking about. You have to mess with the fuel settings quite a bit with elevation changes, with the bridge you don't.
