Power loss, but no cel

Power loss, but no cel
My girl's IS has a lack of power up in the higher rpm range.. After 4k I feel the car starting to struggle. I've done a tune up and it helped, but it doesn't feel like an IS should. Car runs ok in the lower rpm range but I can tell it's not like it use to be. The car idles fine too, so I'm wondering if anyone has had this issue? Any ideas are welcomed since with no cel it's anyone's guess at this point.

Aside from that, your issue will definitely be hard to diagnose... When is the last time the plugs were changed? How many miles are on the car?
