Yes, you can install boost control but DO NOT run too much boost with out other modification. My car has Mitsu 4G63T (Evo I II III) engine. Stock boost is 10.5 Psi I can run 15 Psi all day long with pump gasoline and no other upgrade.
If you run in to 16-18 you need bigger injectors and bigger fuel pump.
Run in 20 PSI + you need more injector and fuel management.
