hey guys, have an r33 gts-t, had it for a few months now, it has a front mount, pod filter, and full exhaust, but it seems to be lacking in power, it launches when it first comes on boost, but after about 3000rpm it doesnt seem to be pulling like it should be, it and then sometimes kicks again up around 6000rpm, maybe im just bein paranoid but im sure its something, iv been reading around abit and read a post where the guy had, what seemed like a similar problem, some people mentioned it could be to do with the coils, or the cat, does this sound like that?
thanks guys
