Just got a 2016 fiesta st and like always, I want it faster :)

If a tune isn't enough for you, look for the biggest, best intercooler you can find. The stock turbo has a tiny compressor that spins incredibly fast. It is not efficient which heats the intake charge so bigger is better for the intercooler.

If that is still not enough, you have two options, hybrid turbo or "big turbo". The choice you make depends on budget and what you want your power curve to look like and it is complicated by the limits of our DI fuel system. If you go that way, research a lot.

Accessport, pro-tune, intercooler (biggest one you can afford), meth injection and/or E30 with tune.

THEN 2J racing intake if you can handle the jet sound, if not skip the intake and get a catless DP, then an intake or catback.

FearTheSnail went 11.9 on the stock
Catback. I went 13.3 on the stock intake with a drop in filter.

If you truly have more than 220whp in mind, you def need to seek another turbo. How much power you want and what you can afford can lead you from there..
