it sounds like the injectors are on the default min pulsewidth allowed by the ECM, ive had this happen a lot on stock cars/smaller engines with big injectors, like said above apply the .cax for the minimum transient pulse width, it will show up in the parameters menu under injectors....knock it back by 50% or so and it will lean right out......keep in mind your 45% leaner VE in that spot is more than likely incorrect right now you will probably have to put most of that back in
