    2011 Datalog Boost vs Cobb Specs

    Hi guys,

    Just getting my feet wet with datalogging with the Tactrix cable and RomRaider opensource software. I'm completely stock 2011 WRX.

    I'm logging 14.07psi peak boost on a 3rd gear pull.

    I've read anything from 14-14.2psi on a stock tune.

    My question is Cobb is showing 15psi on stock. (https://static.cobbtuning.com/cobbtu..._WRX_09-13.pdf)

    Is it possible I have a small leak? Or is Cobb reporting high numbers?

    I don't have a stock '11 ROM. Pull the map with ECUFlash and look at the Target Boost table.

    Ya, I didn't create an image of my stock-map yet. But I logged target boost too. 13.34psi is max.

    EJ257: I pulled the map with ECU Flash. Looks like my target boost is 1.93bar(absolute) ~=13.5psi(relative).

    Old thread. But forgot to followup. Was a boost leak at the throttle body hose. Fixed!

    Currently running TP tune with a nameless DP
