Ok what I would like to know is how close is the spool up between a Q and a P trim 67 turbo. On sites like boost logic and sound performance they say that the spool up is almost exactly the same but the Q trim offers around 50 more top end hp. How much truth is there in that statement? I am looking for a broad powerband so I need to know which is the best to get for my goals. Also are these turbos cpable of making 650+rwhp through a 6 speed? Thanks.
