Last issue with MS. Lean spike on closed throttle.

I have 1 other kink to work out with my MS and i will be satisfied. When ever i am in gear and i let go of the throttle the car pegs lean. I tried to enrich the hell out of it at higher rpms and lower MAP but that only made me rich at light throttle but still lean when i completely let go.
Any suggestions?

Why do you not want it to go lean in overrun conditions?

Set "Over Run Fuel Cut" to OFF under "More Settings".

when you let off the throttle, if overrun is enabled, it cuts fuel.. so duh it will be lean?

Is it safe crusing at 22.4:1 with 0 throttle? Also, i do not have overrun enabled.

Every msq you posted yesterday when you were bitching about it going lean, you had overrun turned on. So unless you just turned it off, it's on.
