Hi-flow cat will be my next step. But what is confusing me is how every other results I've seen from 32,33,34 GTRs and they say standard boost and everything and they made 180-200ish. Just thought how could I be 30kw down from everyone else? I just was abit thrown back when I heard 160rwkw. I mean for a 2.6ltr TT that seems very low, RB20 with a few mods wouldn't be far off it.
