RX8Club.com - Maybe a Newb question?

ok i have 04 RX8 with a greddy turbo kit, ultimate e-management sys, and upgraded rs bov, and since ive had it , it has been running Extremely rich. To the point where i can smell the damn gas. Anyways had a guy supposably tune it and it ended up dynoing 212hp, but made the comment that he tried to change the mapping on the gas but as much as he changed it, it would not lean out at all. so my question to everyone is, do any of you currently have the same problem? if so how the hell did u fix it. and anyone know any good tuners in the bay area? san franciso, LA, SanJose, Hayward, Monterey? Sorry im am extremely new to all this...any help would be greatly apprecaited...
