headers drop boost pressure?
So, I've confirmed a drop in boost with my OBX headers. I lost about 1 lb on my 5.5 psi pulley (currently maxing out at 4.5 psi and spiking to 5 psi on my gauge) after I ditched the oem headers/dats y pipe/evo2 for the new OBX headers/OBX y pipe/OBX 3 in exhaust.
I've acquired that this is normal, for opening up the exhaust to drop boost slightly? I haven't made any other changes, just the exhaust system, and instantly lost .5-1 lb of boost. Planning on installing the 6.5 psi pulley to get back to 5.5-6 lb of effective boost and spike to 6.5 lb. Is this the right approach? Anyone else seeing the same thing?
