Ok, i dont know if this is the right place to be taking about this but i'll say it anyways. so i went to the dealer 'cause my car had the "engine light on" and when i was there they told me that they were gonna flash my car due to some recalls they had with previous cars. the new flash according to mazda will increase the horsepower. after they give me my car back it feels stronger and accelerate faster! could this be possible? or i just feel this way 'cause they told me the hp would increase? the car feel porwerful which is pretty good but for some reason before i was getting 21-22.3 MPG and now i can bearly get get 20MPG now im about 19MPG anyways thaks for reading this>

PS. sorry for the grammar my english is not too well
