Maybe with the cogs +2 PSI you are ok? The impeller should be another 2 PSI and boost comes in sooner in the RPM band and more PSI then also, I was reading over on the Cobra forums, Guys were seeing double the boost at 3k, " Say they where seeing 3 PSI @3k after the did the impeller they woud see 6PSI at the same 3k"
