RaMpAgE R33

Hey all i just signed up, i bought myself an r33 gtst (LOVE IT) i have a problem i was wondering i could get some advice on! since i bought the car it will only run upto 5 pound boost or less. I tampered with the plumbing and managed to overboost the car. I have changed it bk since. i am going to wire the solenoid 2 moro to give constant 7 to 8 pound boost and see if it acually works, gets it upto my desired boost level. any help would be awesome!

Hey all i just signed up cause i got a 94 r 33gtst Just askin but when i got the car it wont run over 5 psi i tried a little pipework and ran it wayyyy past 7 pound cause the overboost mechanism kicked in lol. (put it back soon after) i wanna do the wire job to test it but does neone have an idea on what could be wrong with my car?????
