SO i have recently installed a TIP, Blinktek heat shield, ebc running in line with n75, aftermarket filter, milltek exhaust. 1999.5 1.8t nDBW

SO after hooking the ebc in line with the n75 my car will only boost around 9/10 psi. i could turn it up on the ebc a little but it would only give me till 14psi. I have no boost leaks. Im currently up at altitude 5k ft. and its 40 degrees.
It would boost around 15 with just the n75. and when i went home to california i was hitting 17. Let me know what you guys think i should do. im curious as to how us Drive by Cable cars can up our boost because we have no MAP sensor.
