2011 Datalog Boost vs Cobb Specs

[PBallen]

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?

Am running 93 too

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).
