Is the TBE still on the car? and if so, is it tuned for it? Because if not then you will want to do that ASAP.
The AP is a great tool, not only for a little extra power, but also to monitor your car.
Next I was say to get a catless UP, it will be safer because you remove the cat in the UP, and it will give you slightly quicker spool.
Good luck! Blobeyes are the shizzzzz

Yeah the TBE is still on the car, as far is it being tuned for the car im not sure about that. So the AP is a good buy then? and the catless UP was next on the list..on another note the exhaust isn't loud at all almost like factory and it has a full exhaust, any idea why?

If its a prodrive exhaust, its similar to the Cobb and Perrin, looks like stock and is just slightly louder than stock (which to me is a good thing) I run a full Cobb TBE and its not much louder than stock at idle, and doesnt get loud until Im deep into the RPMs. I run a Cobb AP and Im tuned with a 20G turbo and supporting mods. So even if you plan to go past stg2 the AP is a great tool. I regular use mine for monitoring my boost and a couple other parameters that it holds, plus it has the ability to check for engine codes, other modes like valet and what not. Its a great tool and worth the money IMHO, and with your car its pretty easy to find a used one for cheap, just be SURE to make sure the AP is unmarried formt he previous car or you will have issues.

Yes I would definitely get the AP stage 2. I believe you can buy the AP (used) from Cobb. This is sure fire way to know you are getting an unmarried AP. Price may be a little higher then buying one from someone but at least you know what you are getting. I would also take a look at your "spring" set-up. Maybe moving to coilovers would be a get move for your performance and handling.

I agree with you on the fact that it is a great tool. I use my almost daily. I wish someone could make a mold of it and then have a mounting unit that you can slip it in and out of. Something that you could permanently place in the vehicle.

I got a cell phone holder (from Best Buy) that has adjustable sides on it. Clipped it to my center vent, and it now holds the AP. I )just ran the wire down the seam of my center console, and then up underneat my steering column. I dont have a pic on this computer, nor am I anywhere near my car, I will see if they wife can find anything to show it.

yeah its prodrive im sure of that, and im just used to my car being somewhat loud had a mustang and it would scream wide open could I possibly change part of the exhaust and maybe make a lil louder without losing power? But im definietly gonna order the AP in the next few days..any advantage to gettin one new over used havnt really seen any used..but if i could get the exact same thing for a couple hundred cheaper that'd be great.

There is no downside to getting one used, as long as you are sure it is unmarried and has all the necessary components. Anytime Cobb updates their software, it can just be downloaded from their website right to your computer and AP. I bought mine used and did this and I have had no problems with it. Plus if you plan to go past the basic stage 2, they have maps for different setups, or you can even get a protune with it at most places.

Sidenote: I would drive carefully if you aren't sure if it is tuned, or talk to the previous owner and see.

If you know it has a DP, check to see what type/style the end is that connects to the CBE (cat back), then just get you a different cat back for the car. Thats your basic noise maker on these cars.

Hey Dylan, I also have a 2005 WRX. I started with some pretty simple things that made it a lot of fun, then just recently took it a bit further to make it pretty damn fast too

The first mods were:
Complete exhaust with ported headers, catless uppipe, catless downpipe, wide open 3" all the way back. I dont have any cats, (still legal in Nebraska) or a muffler. I did a port and polish on the stock turbo, put some samco intercooler hoses which are smoother and make for a little bit quicker spool, and dropped in a K&N panel filter. I still use the Cobb accessport, and I used their standard 91 octane stage 2 map. The result at that point was a really quick spooling turbo with a mid range torque curve, but I noticed it let up just a bit above 5750rpm or so. Still, a VERY fun car to drive. Logged a 0-60 in 5.2sec on a hard launch.

Recent mods include the vf39 turbo from the STI, also ported and polished, STI intercooler, and 600cc injectors. The bigger turbo should in theory have more lag, but the PnP, along with the bigger intercooler, pretty much eliminate that. I have also swapped the flywheel for about a half-weight one, and a heavier duty clutch, both by ACT. The lighter flywheel really helps all around response. Don't go too light though, like race-spec or whatever, as it will be way less friendly to drive. I still use the COBB map, but it is different for the bigger turbo and injectors, and has some issues that I still need to fine tune out of it. The result here is still a very quick spooling turbo, maybe just a hair slower but not so you'd notice, but it doesnt drop off at the top end, just keeps on pushing all the way to redline.

Cost of parts for the first stage:
Didnt have to buy anything for the PnP on the stock turbo. Just a dremel, and I had my mechanic do it because he has experience.
The full exhaust (catless u/p, catless d/p and straight pipe to the rear) probably cost about $300 (generic parts from Ebay, makes no difference w/ just straight pipes)
K&N filter was about $50
The AccessPort will cost whatever you can find one for.

Not very expensive, very fun, reliable, and still very driveable. Smaller diameter (but not TOO small) uppipe helps too, keeps exhaust gas velocity high as it gets to the turbo.

Next stage of upgrades:
vf39 turbo i got for $400
STI intercooler was $240
600cc injectors were $190

With whatever labor, unless you can do all of this on your own.

Still pretty affordable, Quite a bit faster car, still very reliable/driveable. A little bit loud in my case, but not nearly as loud as some, bearable.

Anyone else, feel free to throw in anything I've forgotten, and I will do my best to respond.
Hope it helps, feel free to email or PM any questions you have.

Prodrive doesn't make TBEs.

And if there is a full exhaust on it, you better as hell hope it's currently tuned.

Been hard pressed to find WRX's in Wichita Falls myself.

Hit me up I'd like to help you out I do alot of the tuning myself. It's alot more fun when you can compare a couple and the mods you got.
