Default Poor performance after 7500 mile service

Hi, all:
I had my 2006 Volvo S80 serviced at dealership recently. It's 7500 mile free maintenace
including oil change/filter change and other checks.

Immediately after the service, I noticed substantially degraded performance, namely:

1: car gets slower, i.e, need higher engine RPM to accelerate,
Especially when I start from still, I need push engine up to 3000 rpm to get a feeling of acceleration which I used to feel near 2200 rpm

2: at flat highway with engine speed 2000 rpm, the cruise speed used to be 65 mph, now it becomes 62 mph,
3: fuel efficiency is down by 10% (tested through 300 miles daily commute under same road conditions as before).

Now, I feel the dealer may have done some thing bad to this car either inadvertently or on purpose.

Does anyone has similar experience after the 7500 mile service ?

Thanks for your input.

Take it back and have them check it out.
It may need a software upgrade.

A 7500 service is nothing more than a glorified oil change. I doubt they did anything to effect preformance, but if it's under warranty take it back and have them look at it.
