I own a 15 Eco boost with performance package. I drove a base GT but liked the balance of the 4. Also I always modify my Mustangs ,I have owned several, and the 4 is very easy to make power from bolt on's. According to American Muscle a JMS boost control will add 40-50 hp. Roush claims 29 hp with a cold air kit. SCT tune adds 30 hp. All of them together don't make the claims individual advertised but they will make around 60 rear wheel hp for around $1200 . That is about 80 hp at the crank taking the Mustang to about 390 hp. American Muscle car with these mods is running in the 12's. It is a lot of fun to have a 141 cubic inch 4 running that fast.
