Hey, First time posting, looking for some insight. I got a Spec V with 150k and when it gets to about 5k rpm it almost acts as if it hit the limiter in the way it falls off In power. My car friend drove it and mentioned it seems like it's leaning our who is his "Nissan's version of v-tec" as he put it. It's not injector or pump because the guy that had it b4 me left the old pump and injectors in the trunk. If anyone has some useful tips pls do tell.
