I have the TSI kit on my 03 OZ and today i installed a boost gauge and a Turboxs MBC. I made a T where the wastegate goes back into my turbo and put a hose from that going into my MBC the other hose is T'ed into the Hose goin from my intake manifold to my BOV. I turned the boost to 7 and im still reading 3-4psi i even reversed the tubing on the MBC and all it did was make my vaccum max at about -10 - 16 So im pretty sure this is the correct way to do it but why wont the boost go up? Would reseting my ECU fix the problem? My car also has weird idleing problems and if anyone is familiar with the little ECU thing that comes with the TSI kit could you help me understand it?
