Hey there fellas!

So I just got my 8 back from Mazda today after they replace the engine and cat, both covered under warranty. I must say, it feels like an entirely different car!!! I bought the car for a year ago, and the car had pretty good power, but nothing special. All of a sudden my car lost almost all of its power and rpm range which led to me getting a new engine and cat. The car has so much more power than when I got it a year ago! I'm scared that maybe the power will fade away and the car will be just average again Is there anything I can do to make sure I always have the power that I do right now?

Thanks guys!

 

Also, do these engines need to be broken in? The warranty engines are rebuilds, so arent they already broken in?

 

Supposed to be broken in. But, just for luck, follow the new car break in procedure.
