    But the stage 1/2 is $145.00 wouldnt that be better money spent instead of just buying a stage 1 for $85?

    Well the way the warranty works is, you modify something that causes something to break your out of luck. So let's say you only buy springs to lower the car and you blow a strut, well that's on you. Same goes with engine mods, you tune your car and the engine gets a spun rod or something, they could deny your claim.

    I'm not saying that's exactly what's gonna happen, I'm saying it COULD happen so be ready.

    I would disagree on that but everyone has their own opinions. Eric does good work but there's a limit to what you can do with an
    etune. Having someone dial in your tune while watching live data will almost always yield better results

    I would not. It's $600 that would be better spent elsewhere. A tactrix cable is less than $200 new and does the same thing. Then you could do a torqued performance tune if you choose, or go protune, and romraider and ecu flash software is free.

    Tactrix cable...Tactrix Openport 2.0
    Romraider to download (for logging)...RomRaider - Open Source ECU Tools | RomRaider / Download
    ECU Flash (for flashing your ECU if you are planning on buying an e-tune, like torqued performance)...Download EcuFlash

    Yes, you can always flash back to stock. ECU Flash will allow you to save your stock ROM.

    Here is all the information you'll ever need, a ton of great info...OPENSOURCE TUNING: Your questions answered here!!! RomRaider + Tactrix

    You can flash back but Subaru will be able to tell you flashed the ecu. I found this out yesterday after talking to my dealerships senior mechanic. He explained the process to me but all I got out of it was they take information from the ecu and send it to Subaru to determine if it's been flashed. He also told me to leave the car as it is and to stay away from any mods because of the potential to ruin my engine. He did say a cat back wouldn't hurt.

    Yeah I sure they would be able to tell anything you did to the car. JD I dont anything about open source tuning I think a cobb would be better if I were to do it at all. Warranty really worries me.

    If it worries you that bad keep it stock. The car is fast just like it is. To need to talk to your dealer and see what they say about modding

    A lot of people have the accessPORT (I had one for a while), they are a great piece and super easy to use. Some downsides are they are expensive and the included maps are "one size fits all" so they leave a lot of power on the table. Going protuned, you don't have to buy the equipment (the tuner will have it) and is custom tailored to your car. Either choice is a good one though.

    Any way you cut it, if you mod your car, you risk warranty coverage. Even with an accessPORT

    You can get pretty close, with proper monitoring hardware. I'd prefer to have the tuner in the car, personally.

    One advantage of a custom dyno tune is that you're not doing repeated WOT high-speed runs on public roadways. There should be a checkup/cleanup on the road afterwards, where you will be doing them, but you can get the tune dialed in pretty well in a controlled environment.

    I wholeheartedly disagree. a Stage 1 protune would be an excellent investment if someone wants to really improve the driveability of the car, without being ready to add parts. You can net gains of up to 15% more whp/wtq or so just by adjusting fuel trim, increasing boost, and toying with the timing. The stock tunes on Subarus are notorious for being crappy and on the lean side, as well as filled with some flat spots. A protune can completely change all of that. I especially would validate a protune at Stage 2 levels. Again, nothing off the shelf can compare to a full dyno and road tune. Everything is tuned specifically and optimally for the DP and whatever parts you have on it. It's not just reading logs and adjusting for that. My Stage 2 protune was the best investment I made on my last STI. Stage 2 levels I was putting down 310whp/330wtq and was capable of a 12.3 quarter mile.

    But technically, a TP tune is sort of a protune as it's not just a generic OTS map that everyone uses. You get that level of adjustment necessary for any parts you may have or for climate/altitude. It gets more specific where as the Cobb OTS maps are just maps for everyone. FWIW though, especially for the $85 price tag...I'd take a TP tune using a tactrix cable over a Cobb OTS tune anyway, for price and for the minor level of adjustment you get provided.

    That's sound advice if you are concerned with the warranty. Look at it this way, you may never need warranty work, but if you do.. it pays to be on the straight n narrow.

    I didn't tune mine until 60K mi so warranty was not an issue. I will say though that the ap and tractix/romraider are only interfaces to tune with. Neither has an influence on the quality of tune.

    Like any open source software/hardware though there is no support other than web forums and personal opinion for the tractix/romradier route.... its on you to maintain, troubleshoot.. etc. The only advantage is cost savings. If you're computer saavy and can confidently work software/hardware config.. this is a much cheaper alternative.

    The Cobb AP isn't cheap, however does come with lifetime support for software and hardware. You get access to their other software products as well as their online forums. This is why its more expensive. They also include ots (off the shelf) mapping for free with the AP as well as being able to access their website to grab other ap maps for popular bolt on mods. These are good enough for most but remember you dont have to use them. You can install an AP and go right to a tuner to have a protune done.

    so its purely up to you which interface you choose. Everyone's needs are different. One isn't better than the other performance wise, but they are individualy better or not better for each user depending on needs and useability. Most often, people choose whatever their local tuner prefers. That way they are open to protune when they decide and dont have to change up or give up the interface.
