Default Update on Overboosting with n75 and mbc

So I got the 710n DV installed in the car. I take for a ride once with the n75 and then with just the mbc. Leting off the throttle was a lot smoother thanks to the 710n DV. But I still had spiking issues of up to 20psi. I decided to check the Wastegate actuator to see if it's working. I unhooked the vacuum line to it and opened the throttle to see if it would move the wastegate rod and nothing happened it didn't move a slight bit. So there I knew my wastegate was my problem and not the N75 or MBC. I decided to remove the WG acuator that came with the K03 hybrid and replace it with my old stock one. Funny thing was when I try to install it the bolt holes didn't line up. So I took a F&^kin fit saying the turbo was a Piece of ****. I then try to install the one that came with it and to my suprise it didn't want to fit either. Thats when I realize something was definitly screwed up. Turns out the compressor housing wasn'tlined up right. I had to loosen the bolts and turn it enough so the WG acutar rod would go in smoothly. Sure enough the bolts lined up and the rod slipped in perfectly. From the housing being off it put preesure on the WG rod and stopped it from opening. Who ever built the turbo was probably sleeping on the job. My spiking issue went from 20psi to 10-14psi car runs a whole lot better and running with the Turbosmart MBC knock off. Which is giving methe 14psi spike every now and then but that is the MBC for sure. Will replace that with a turbonetcs unit. Thanks for the help guys it's just funny when it turns out to be what you least expected.

Yeah it wasn't clocked right. I got it from Advanced JDM it says it's german build but the price is what made me skeptical. But being in the finacial state it was all I could do.

Yeah ain't that a bitch.The stealership would have smiledand said would you like some wine and lubrication before we proceed to service your vehicle. Don't worry it'll hurt just a bit.
I got to say the little bastard turbo is pretty decent I had that thing at 20 psi running lean with the actuator stuck and it still didn't blow up. Lucky me. Hey you get what you pay for right.
