Ok so I have the fuel managment options answered I think and now I am wandering about the pair valve. I see a kit for block offs (2 plates now as it was 4 on 07 and below) and a plug of some sort that might be optional? So I guess my new question is...are most removing the pair valve and blocking the two ports and is the plug optional? Seems in looking at the block off plates that they don't all come with an what I think might be an o2 sensor plug or airbox plug. Sorry for all the questions but want to order what I need in advance before I do the exhaust install. Lets here what everyone has done and thanks in advance... again.
