theres ur problem now with a wideband u have to be carefull if the motor is going way lean it can give a false rich reading on the wideband.
same goes for the other way around.
so go into ur ve map and take away a lil fuel in the area were its going into 9afrs and see if it helps , if u take away some fuel and it gets worse then u know its a false rich reading and u have to add fuel instead
what fuel injection system did u say u were using, if u need it i canprolly lend u a hand getting the thing tuned and looking at the datalogs
