Hello,

Id like to ask what's the next stage of tuning focus 2015 1.6 tdci 95hp. i've done a chip tuning, now it's ~135hp, and dont know what next stage? What should I replace? What's the efficency of turbo or injectors?

well engine power if fuel so if you need more fuel = bigger injectors , also in order to burn fuel you need more air = bigger turbo , also check if the rest of the car can handle that much increase in power so if needed upgrade other components (like clutch)
