reading this made me feel better... i'm from seattle which is at sea level and am up in about 6800 ft in wyoming and feel like my car was messed up from the drive... i didnt really think about the altitude affecting the turbo so much..
so anyone else who goes to higher altitude, expect to feel sluggish and dont try to pul out into traffic as fast as you normally can

Hey guys, few questions from a newbie in SLC. I bought an 08 WRX a few weeks back, only had about 15k. So far the mods I've discovered (might be more) have been an Agency CBE, TurboXS RFL BOV, and a Cobb V1 tuner plugged in to the OBDII. The accessport is nowhere to be found so I have no idea what kind of map is installed. I found the window sticker which shows it was sold in CA so I'm worried the tune was set up for a lower elevation. Anyone know if any accessport can read the map or if there's a way to reset the ECU to stock without retuning? I've never used the handheld tuners before so this is completely new to me. Any advise would be great
The engine tuning forum would be better for this post! Welcome though!
Are you sure about the V1 tuner? The 08's ECU is CANbus, which was only supported by the V2. Can we get a picture of the tuner you're talking about?
The thing is... that sounds like the Accessport V2's first revision dongle. The second revision of the V2 uses a black dongle.
It's grey plastic with a usb-mini port in it... red "C" logo, and red plastic where it actually plugs into the OBDII port... correct?
That's the Accessport V2's first revision... that's the one I have.
It sounds like that's the one. So when they said "previous version" they must have meant the first V2 and not the V1. So now that that's figured out, without having an accessport tuner, whichever map is programmed on my ECU is stuck. If I were able to borrow a local's accessport would I be able to find out which map I have installed, and if not would a pro-tune be worthwhile to reflash my ecu? I'd like to be able to return my ECU to factory since I could be tuned on Stage 2 at sea level for all I know, however I'm not sure what methods could successfully return to stock settings.
Before you go messing with your ECU... you need to find out what exactly you have installed on your car. If you replace the map with a factory map, and you have an aftermarket boost controller, or downpipe with a protune... then you'll have one pissed off car.
I'm fairly certain a boost controller isn't installed, when I first got the car a boost gauge was installed and I was getting 12-13psi max. Since then I had to remove it since it was blocking my speedo (terrible placement ). As for the DP, I got under the car and checked it out, it's definitely stock, so it would appear a CBE and BOV are the only mods installed which should be fine with the stock ecu programming. Any suggestions for how I could return to stock? I'm still under the 3yr/36k so I don't want to go to the dealership for fear they'll void my warranty. One reason I'm adamant is because since purchased my gas mileage has sucked (16-19mpg)
