Greddy Profec OLED

Hi there.My name is Elias and i am from Greece. I am an Evolution 9 owner and i just bought EBC (greddy profec oled) before i flash my stock ECU and i want to ask you if its nessecary for my specs. My car has forge actuator full intercooler kit, HKS induction, 340aeromotive fuel pump, full exhaust(76mm to 80mm) and i am planning to upgrade injectors and camshafts later.My engine is stock. As i read that this EBC doesnt have the option to tune boost per gear or rpm specific without MAP extension. Stock ECU has this option and i was wondering if this EBC is useless for me like some people say or its ok to flash my car with this EBC. I need your help guys please!

Itís fine to use it but as it doesnít allow gear/rpm boost control, you wonít be able to fine tune the boost.

Ok, ECU-Boost is more flexible and if you use a quicker solonoid quite as fast as the Greddy.
But with the Greddy you can flexible switch between 2 settings and have an overboost button as well. With Tephra it's also possible to swicht between two settings, bur if you ****** bad petrol you have to reprogramm your ECU.
