Engine Vibration

[matt08ms3]

I am new to the mazda seen. i just got a 2008 ms3. It had 18000 miles on it when i got it. I use it as a daily driver. Anyways when i am driving on the freeway (mostly when it happens) when i spool up the turbo, give it gas to pass, whatever, then i let off and use the gear i am in to slow down the car when it goes from about 4500 to 3000 rpms the engine vibrates a little more than normal. It only does it when i spool up the turbo. It usually happend in 6 and 5 gear sometimes 4. Any ideas? I dont know y it does it? Its not like a violent shaking but you can here and feel it.

could be mounts

might check your tires

at 18k, do you still have a warranty? might want to let them figure it out for you for free if so.
