18psi is the target, and it holds pretty well, just barely starts to drop off maybe to 17.5 on the gauge at redline. To be honest I barely ever run the car up that high, most of my power occurs prior to 5500. I credit a lot of that to modifying the hood scoop and running the bigger OEM top mount from a 2011 STi as well as the EL headers and exhaust wrap. Pressure drop is pretty negligible. I want to see how hard I can push the car with a stock motor turbo and fuel system with just tuning and bolt on improvements.
