    I've seen it boost up that high but normally it's 16.4-17 psi

    That that amount of overboosting, I would attribute your loss in power to your car pulling back the DAM a ton in an attempt to keep your engine from blowing. The Cobb map is not tuned for that much boost, so you were probably knocking like crazy.


    Just out of curiosity, what is your DAM at right now?

    Please explain DAM. not to familiar with that. Even with severe low waste gate map on it'll go to 23 psi at random points but not all the time

    You need to check to make sure your wastegate arm is operating freely. Youre about to have serious issues and need to stay out of boost until you correct them.

    Dynamic Advance Multiplier. Basically, there are multiple tables that account for the Ignition Timing; that being one of them.

    Total Timing = Base Timing + DAM*Knock Correction Advance (where things like compensations, feedback and learned knock, etc. all come into play). DAM is a way to pull timing globally across a wide spectrum of RPM/Load cells, when the ECU feels it's necessary to.

    How do you check your waste gate arm is free. I'm not too advanced for this

    Anyone know a good DIY I could use to remove the gaskets on the IC-tb hose. I just don't want to screw things up

    Get socket set. Find sockets that fit bolts. Use long flat head screwdriver to unscrew TB hose clamp. Unbolt bolts on turbo and on right side bracket. Use plyers to loosen BPV hose. Pull off BPV vacuum line. Pull off TMIC. Carry on. Rinse, and reverse. Done.

    Put your bpv back on before you hurt something. You can't run a bov open atmosphere with a cobb ots tune
    2013 WRX sedan - MODS = pretty much every bolt on besides a bigger turbo.

    As long as the BOV is installed and functioning properly it shouldn't be any worse than running an atmospheric BOV with a custom tune.
