Default Fabspeed intake, car feels slower???

Just installed Fabspeed intake on my 09 c4s and while the sound is "better" seems like there is a decrease in throttle response and car seems more lethargic and heavy. Anyone had this experience? I want to like it but think I might take it off.

Ps I just read new post by member who did a very interesting comparison of stock vs fab and fab showed favorable comparison - confused

Dyno it, remove it, and dyno it again. Then report back.

Have the plenum and intake on mine. After intalling the intake it felt better on the upper end hp-wise, now with the plenum it feels like I need a tune. So maybe that is the third ingredient. If you simply dyno it now and tune then dyno again you'll have no question.

I would recommend a tune, always, but if you talk to someone at Fabspeed they may be able to help you out. If this is a common occurrence I would think they have handled it before. If it's not a common occurrence, maybe they can help you figure it out.
