Hi all alright so I just got my new turbo on my sr it's a built sr with stage 1 264 cams 550cc injectors fpr front mount all that jazz. I was running an Isis 3871r turbo which is garbage invade your wondering I had 2 blow up on me. I switched to top mount and am now running a t04e from turbonetics it's a .48 A/R. The manifold I bought came with a bung and a fitting on it that looked like you would put a vacuum line in it I plugged it instead after searching and finding nothing. Now the car doesn't create boost I don't have a reading from my boost gauge there are no vacuum leaks and my bov doesn't let off. Any suggestions ? Thanks

Internal or external wastegate? Are you running a boost controller? Is your boost gauge reading vacuum?

External waste gate, it's not stuck open neither is the blow off valve. The boost gauge doesn't read vacuum only boost, but the blow off valve does release pressure but very little almost like a mouse is coughing on you. The car runs like s*** when the safc2 isn't correcting the a/f it's an ecu tuned by Enjuku for d1 also tried a central 20 tuned ecu didn't run Much different

A boost leak or a vacuum line routed improperly...

IF two different rom tunes ran like s***, I'd really start looking into the vacuum lines, timing, and anything else related to the engine.
