Ka-T Running Rich

[schug13]

Recently swapped sohc to dohc turbo. SAFC installed, stock maf, a/r .50 turbine housing, 370cc. Idles well. I don't have a wideband so there is no way to get an accurate a/f reading, other that reading the o2. But I can smell the vehicle running rich at idle, and a problem I have not been able to get rid of is: while driving, @ a non certain point of throttle, it just seems to not do anything, its not bogging down. But if I push the throttle more it will open up and take off. So somehwere in between low throttle and high throttle I have a problem. I do think a hotter spark could help this some ( still have stock ignition) msd perhaps. It is only at five pounds of boost. Any ideas?
