    I am going to be honest.. .I am new to Subbies but not new to turbos and tunes (still waiting on my WRX) coming from a tuned Volvo S60R.

    Typically what I have seen with boost levels not holding pressure in higher RPMS could either be:

    1. Turbo Control Valve?? Not sure what they are called on Subbies or how they work on these configs but usually with the newer turbos there is a valve that sends the correct amount of pressure to the turbo. Similar to a boost controller back in the day but that was to manually control boost.. this is a solenoid valve that is controlled by the ECM. If this car has one, maybe that is only good for stock boost levels and needs upgraded?

    2. There could be a small leak in your intake system causing a loss of power at higher RPMS

    3. Do these turbos have a control bypass valve (CBV) on the turbo... typically where someone would install a blow off valve? If there is a diaphragm in the CBV... that spring might only be rated for stock boost levels and over time wear out so much that it will not hold boost at high rpms?

    Once again I am new to WRX/STIs so excuse my noobness but I am hear to learn

    My car was actually slightly overboosting this morning in both S and S# on the standard SF map (I hit 16.1 and 19.2 PSI) so I'm going to load the LWG map on when I get home this evening just to be safe.

    By the way, the tapering of the boost at high RPMs is expected, here's a pull from their map notes (https://static.cobbtuning.com/cobbtu...AEM_v310.pdf):

    Stage1+Intake 93 v310 Boost Select - Intended for 2012 Subaru Impreza WRX STI vehicles with COBB Tuning
    SF Intake or AEM Cold Air Intake with a stock or cat-back exhaust running 93 or 94 octane petrol. Boost Targets:
    ~18psi (S Sharp) or 15 psi (S) peak boost pressure tapering down to ~13.5 psi by the 6700 RPM redline, +/- 1.0
    psi.

    Stupid question... what is LWG map?

    Have you tried loading your logged data?

    It's a Low Wastegate map Cobb developed for use if your car is overboosting with the standard map. There's also a High Wastegate map if you're not reaching the target boost level. As far as loading the logged data, I haven't logged yet, I've just been monitoring my boost and I've noticed it exceed the allowable limit a couple times...no since in risking it since this is my DD.

    Welcome! Great car man. If I were to mod anything I would absolutely get a Accessport first.

    cool on the short shifter, you will love it. It was the best mod I ever did on my old car. My new WRX comes with the STI Short Throw but I assume the bushings dont come with it so I will be updating the bushings as well. The bushings are what makes a big difference in feel... you sound like you got the short shifter rod kit and then another short shifter trans mount kit as well?

    ya for sure, looks like you got the whole shibang kit there. The small 4 there look like bushing replacements for the actual shifter housing base... the 2 AL shafts are your shifter assembly...

    here is a link to the Perrin which might give you some idea on references... looks like the rectanglular bushing goes underneath the car?? PERRIN Performance — — Rear Shifter Bushing
