You should run the map for 2012 WRX stage 1 with AEM intake and the fuel octane you plan on using (the "ACN" map if you live in Arizona, California, or Nevada).
I live in new england. Any idea what map that would be or where i can download it

Go to Cobb's website. They list all the available maps on their site. Read each map note, if your intake is not listed in any of the notes you've got to find either a performance shop to tune it or pay for an etune

Stage1 AEM 93 v334 Boost Select HWG.ptm

Stage1 AEM 93 v334 Boost Select.ptm

Stage1 AEM 93 v334 Boost Select LWG.ptm

Which one out of these 3?
Depends on if you are missing your boost target set by the map parameters, but yes one of them

So just pick one and make sure im getting the right boost. Like 15 psi correct? Im all stock except the cai and cbe. Also how do i download it to the ap do i need a special cord. Sorry im new to this tuning stuff
You download the map and connect the ap to the computer with a usb cord
Read the map notes provided on Cobb's website. Those give you all the information you need.
Allright thanks guys your the best
I would try the normal map first (Stage1 AEM 93 v334 Boost Select.ptm).. if you're overshooting the boost targets then try the "LWG" map. If you're undershooting boost targets then try the "HWG" map.


To download the map, first download the Access Port Manager software. Then I would update the AP before putting the map on it.

Allright thanks man im just waiting on a new usb cord because apparently none of the 50 cords i have fit lmao. Stage1_AEM_93_MTv331.ptm is also a normal map just wrx correct? Think i posted the sti maps

Yeah.. it looks like 331 is the most recent map revision for the WRX. It took me some hunting (someone at Cobb needs to update broken links on their site and nasioc threads), but I found the page where all those maps are hosted. https://cobbtuning.zendesk.com/hc/en-us/articles/204448184
It also took me forever to find that same link lol thanks brotha. Im hoping for a 20 whp, you think thats realistic?
Cobb's notes tell you what expect if I recall they recorded around a 10% gain
