Weird lag under moderate/hard acceleration?

I've been driving my P5 for about a month now and am not sure if this is normal. It feels like the problem is in the higher RPMs under moderate and hard acceleration. The clutch is good, just changed out the spark plugs with correct gap and changed one coil pack with no change in behavior. The best way I can describe it is like turbo lag. It still pulls and runs well, just not perfect. I was thinking about tackling the fuel filter next. Maybe checking the engine/transmission mounts too?
