I have the GTU running well enough to pass smog, but theres something not right... its not getting enough air down the split air pipe. The cat is being superheated at times depending on the driving conditions. I have seen some smoke from the cat from time to time.. I can't sell it to someone this way so I want to fix it.

So I read and read in the FSM only to find one or two decent vac diagrams and they don't really cover that side of the manifold very well at all.. Its really hard to see which exact ports wires up where (for that section of vac hoses)....

So here is what I have:




If anyone can confirm this is correct or correct me that would be awesome.. Those of you out there with stock S5 N/A's I beg for your help.

Here is the FSM vac diagram I found to be most helpful:



As you can see its pretty hard to figure out (maybe not, could be just me) where those ones go in that section of the manifold...

Thanks,
