Interesting attempt to fix, but the DME is programmed for left and right bank... so just swapping O2 sides doesn't resolve issues as a whole when you have mixed left and right bank outputs.

From what I understand... The DME responds to A/F changes in a precise measurement by measuring the output after each cylinder fires. The TU manifold defeats the ability to properly compensate for 4 of our cylinders without significant tuning of the DME stack.
