I hear they have one of the better sounding ecoboost exhausts
You need to take a listen to the HeartThrob! I can't stay out of the damn throttle!! It has such an intoxicating sound in the upper rpm range!!
 
You technically don't "need" a tuning adjustment for an intercooler. However, you will see better performance if 5-Star adjusts your tuning to take the intercooler into account.
Do I contact Stage 3 or 5*?
