I've asked the question before and received deafening silence as a reply.
I replaced the 2ndary cats with have high flow cats. I tried stage 3, then stage 2 but didnt seem any faster or I wasnt comfortable with those maps, so i went back to stage 1 which feel just right. I didnt do any log though. BTW, I have Rev I.
