Trying to figure out what the important things to do are. My 2013 Focus ST has a Steeda FMIC, short-shifter, 3" MBRP cat-back exhaust, high performance air filter, and the Steeda sound symposer delete. In my research I see that a lot of people are replacing the rear motor mount, I assume this is to give better throttle response, and seems like a relatively inexpensive option. What else is next? What are some tuners that you guys are using? I don't need the most extreme and expensive option, but something that will add some power. Also, I drove 350 miles yesterday on the highway and only averaged 25 mpg, but was able to get much higher than that in town driving carefully. I was kind of hoping that I could increase power with a tuner and also get some better mpgs. Any ideas would be much appreciated.
