The only other things I can think of is there's something wrong with the wastegate, n75, or there's something else causing a slight boost leak.

well my gauge shows vacuum when shifting all the way to 30 vacuum is that normal or should it at least boost when shifting even a little?

 

n75 valve i changed a while ago from factory to the n75 racing valve, no difference. wastegate holds suction on the line that comes out. any other way to check the wastegate?
ive found this part slighty cracked, doubt thats the reason.

You mentioned you got new plugs. Are you sure they were gapped correctly? Makes a bigger difference than you would think.

 

i checked the plugs and they were @.038, so i gapped them to .028. cars feels a little bit more stronger, felt the difference right away.

 

Damn! .038!? That is way off. Stock they should only be at .032. Glad it seems better now though

 

That corner hose doesn't have to do with boost, does it? I ordered the piece to replace from ecstuning. Pricey for such a small piece.

 

Corner hose? Corner in reference to what? Pics?

 

The little hose on the ecstuning website, I placed the Website earlier.

 

I believe it will help a little bit if it is the hose I am thinking of. It is expensive though
