Ok so I bought a used evo from my buddy and it has a boost controller that it is locked from AEM EMS(that's what he told me ) .. I'm a rookie in all this but I can connect the car to AEMPro tuner and use it ... It's just I don't know how to open the boost controller and save the calibration in the AEM..(also the car starts really hard .. It takes 6-8 spins to start , he told me it's nothing to worry ) Any help would be appreciated ..
(Sorry for my bad English )
