Sorry for late answer! I was at work. Thanks alot for all the answers. I have been trying to google the answer but still haven't found anything yet, and you all seem experienced so.. . I'm using an aftermarket gauge, i have tried two different ones and both showed the same. Also tested to plug in some old Apexi EBC and got the same boost with that one aswell, that one also showed how much boost i had, and i topped almost 0.4 bar. I have tried a mechanic boost controller aswell but i'm still stuck with the same boost pressure. I'm using the high boost mod btw, by grounding the black cable that goes to the solenoid. I'm gonna check over the hoses again and see if i connected them right. Found another picture on the internet now so i'm gonna try that first, so i'm sure i just haven't connected em all wrong.. let's just hope that it is that easy thou . Thanks alot for the help so far, i'll be back later today to keep you updated!
