Hi Steve. My knowledge of the SEs is a bit limited, but I'll throw in what I can and hope it helps. From years of reading the forums, it seems that the usual cause for terrible mpg on an SE is due to a faulty temp sensor fooling the computer into thinking that the engine is always cold. That's what I would check first.
As far as meets go, in the spring we have the Deals Gap Rotary Rally (NC) and the Mitty Event at Road Atlanta. Both are probably a bit of a drive for you, but worth it if you can make it. For events a little closer to home, check out the regional forum section.
Good luck with your issues. I hope this helps a bit.
