So i got the car done. Noise i was hearing at 2000-3000 rpm is gone. now that the xpz is out that is. i think the problem was the length rods i was running. but idk though i could be wrong as im not a professional(yet). hell it could even been the massive exhaust leaks i was having. Now fixed. The ZZP Headers i have had to be modified. Read my other thread on that. But i have one question. The only thing wrong with my car right now is a vacuum leak because my LTFT at idle shows 16.4. Now i can hear a wistling right by the snout. I previously took the ic apart. I resealed it after clean. Could it possibly be leaking from there? i didnt cake the whole surface with rtv when resealing instead i used a thin coat besides in the 2 bores on the plates for the inlet/outlet of HE i used quite a bit. Should i used a little more to where it squeezes out when the plates are tightened? Also, im using the silicone baking sheet idea as my gaskets. They are cut accordingly for everything.
