i recently removed the whole aiv system off my 91 240sx super hicas and it seems to have lost top end power. i made sure to plug the two small vacuum hoses off the bottom, plugged the pipe that came off the manifold, and plugged off the top that goes to the air filter. it seems like it takes it forever to start building rpm after about 4k i’m not sure what could cause this and i really don’t wanna put the system back on because it takes up so much space please help
