s13 Can removing PAIR valve cause vacuum leak?(injen intake)

!!!KA24E SOHC!!! just got s13coupe as my first project Replaced maf sensor and o2 sensor and tps. Egr block off plate, charcoal canister delete , no pair valve. Injen cold air intake. Since there is no more pair valve I capped the port from the intake near the air filter. Car will run without maf plugged in. Plug in maf = rises in rpm then lowers then dies. ALSO once the maf sensor is plugged in it sounds like it’s sucking in really hard from intake like hissing almost. When maf sensor is unplugged the hissing goes away and the car will idle fine. Should I get a larger air filter or should I replace pair or I don’t know
