  1. A must for any enthusiast

    By Chad August 3, 2018

    This should be the first thing anyone does . Jot just to retune the car but to monitor the vitals of the engine.... must must must have.

  2. Worth every cent and more.

    By AJ October 23, 2015

    Buy it. Do it. You'll be so happy you did. The AP from COBB takes this car to a whole new level. It completely addresses that crazy factory throttle map and gives you so much more. The power band is much more linear, contains way more torque and does not fall on its face above 5500 rpm. 2016 WRX. I live in Denver and am only able to get 91 octane fuel. I am running the 91 Stage 1 HWG map and could not ask for a better tune for my high elevation needs. Before you spend a dime on any other power upgrades, I highly recommended adding this.

  3. Not to bad at all

    By Eric July 29, 2015

    Without a proper dyno or running the car 0 to 60 and timing it, there is no way to fully tell the improvement. What I did notice was smoother acceleration through the entire rpm band. According to the car my mpg was listed at 29.4. When I filled up it was actually 23.5. This is a mix of city and highway driving. My 2016 Wrx also only has 375 miles on it and is still in the break in peroid. Who knows if the dealer filled it full and with 93 octane. Still a good product especially for future mods.

  4. NOT too bad

    By Eric July 28, 2015

    I didn't drive my 2016 WRX for long before I installed the COBB AP. I have noticed a smoother transition through the power band. Is there a huge noticeable horsepower gain? Without timing my runs for comparison and just what I personally feel in the seat, my answer would be no. The car pulls longer and with more consistency through the RPM range however. I haven't noticed any MPG increase and I do stay out of the boost. It might have went up slightly over stock but what the car tells me and what actually MPG is about 3 to 4 miles less. Right now the car says 29.4 on this tank of fuel but after filling up it was 25.4 MPG. That is with highway cruise set at 77 miles an hour also. The car still only has 276 miles on it so I am still in the break in period. Product is worth it for my mods and future ones to come.

  5. Huge difference

    By RexRocket July 9, 2015

    I've owned seven subies so far but this is the first turbo, I traded a 2014 C7 Z51 corvette for 2015 WRX limited (got tired of being pulled over and being harassed by gawkers) I realize this is like comparing apples to oranges but I wasn't impressed by the stock performance of the WRX, I figured the Cobb AP might make a difference after seeing Yo's YouTube posting. Fist and foremost...the stock map was lacking top RPM power as it just seemed to die around 4k. After flashing to the 93 octane map I noticed that it was pulling strong all the way up to redline...this was putting a smile on my face, I've driven it for about 5k miles with the 93 octane map and I'm satisfied overall but have noticed a few things that I don't care for like hard startups, idle isn't smooth and sometimes dips down to under 700 RPMs but comes back up after a couple seconds. All in all IMHO it makes the world of difference with performance both on the top end of the RPM range and noticeable torque increase. I may upgrade to a nameless axle back exhaust to free up the restricted airflow and get some tone out of the 2.0 DIT. I would strongly recommend this product for anyone that wants more power without replacing hardware or having a custom tune. I would love to see them come out with an ethanol or methanol map so I could say goodbye to the big oil monopoly and use a renewable fuel source.

  6. A must for all WRX owners

    By Todd February 26, 2015

    If you are considering buying an AP, just do it. I was skeptical of how much difference something like this would make, but it really is tangible. Definitely worth it, especially for guys like me who aren't going to do a bunch of hardware modifications but want better performance from the WRX engine.

  7. Great Product

    By Steve October 3, 2014

    I have had the AP for a couple of months now. Running v112 map now and will say that from day one the AP transformed the car into near perfect with no other modifications. CAI and Catback and I'm done. As Yo said, this is a "no brainer". Best money you will spend whether you modify further or leave the car box stock. COBB support is second to none, great people and passionate about their craft!

  8. Amazing Product, Fastest Shipping Ever

    By Jay August 26, 2014

    I was so overly impressed by how quickly Subispeed shipped this to me! I purchased on Friday and received the Accessport on Monday. I was blown away! Anyhow, I'm running Stage 1 93 Octane OTS tune and it runs great! Car pulls strong all the way to redline where it used to fall flat on its face. Really smooths out the torque curve across all RPMs. This is a must have for anyone looking to add bolt on modifications (Intake/Exhaust/Downpipes/BOV) or serious modifications like turbo/intercooler upgrades.

  9. What I was waiting for...

    By Richard July 24, 2014

    As soon as I found out this was available, I ordered it up. Expedited my shipping and got everything setup ASAP. Love it love it love it. The car kind of felt dead in the high RPMs before, but now it feels much better.
