English please.
But I understand you want to install a boost controller? It depends on the controller. Most mechanical controllers are nothing but an adjustable air bleed. So just cut the air line to the wastegate actuator and install the boost controller in series with it.
Be VERY careful adjusting it. Mechanical controllers tend to do nothing for a wide range of movement, then all of a sudden skyrocket the boost. Keep it under 12 PSI. You'll likely have to port your wastegate to control creep. You'll need larger secondary injectors like 720CC.
