I read through a couple threads on that mod, it seemed like people were able to get them running right with a tune, but they also were both cross bank manifolds. Because I have switched from two separate banks to the manifolds crossing banks people are theorizing the o2 readings will be off. I have spoken with a local tuner in San Jose who said he will have to license the dme and log it, then see if he can make the necessary changes to the dme logic as far as o2 sensors go. I’m sure there will need to be changes made for the larger twin scroll turbos.
