Stuck seal?
 

So lately i've been noticing my car making power oddly.

Idles fine, purrs like a kitten.

Low revs can't really tell anythings wrong, but it does sound a little different in a cyclic pattern. As the revs go up the noise becomes a little more pronounced and is accompanied by a surge of power. Back to normal, then the stronger sound & more power for just a moment. Doesn't matter weather i'm on the boost or not.

I'll be changing the plugs soon (this weekend maybe) recommendations on plug wires? Diagnosis?

If it idles fine and at low revs you can't tell anything is wrong, it's not a seal issue. What is your vacuum looking like? I recommend going with stock plug wires.

Vacuum is fine @ idle. Boost feels...soggy. (i'm on poor mans nonsequentials) Boosts just like it used to according to the gauge. Just doesn't make the power i'm used to except for on that one "stroke".
