Dan, you got cute kids! (back on topic
That intake needs alot of work considering what you have planned, as already stated. A PCM will not 'help with KR'. KR is something you must battle mechanically. Be prepared to sell the 3.4 and buy a 3.5 if the KR is too high at that point, or be prepared to spend more on PEM'* to battle KR instead.
This is a game we all play. KR is the PCM'* method of protecting the engine from BOOM. If you think of KR as something you cause by changing something, you need to also think about it as something you need to fix (action, reaction) mechanically after the fact.
