  1. Love my Accessport! Soooo much better than stock

    By Kip March 9, 2017

    I picked this up with some mud flaps as my "only" mods I was going to do to my first ever new car. But once I saw some of the review videos on youtube about MAP stage 1 OTS map I pulled the trigger on that as well for only 75. Overall the AP seemed like it was worth its weight in gold...now with the ma performance tune my cobb accessport is worth its weight in Titanium! Happy boostin

  2. Worth every penny.

    By Grigor March 8, 2015

    I was quite hesitant a month ago about spending 600 bucks on this product. I did my research, but still took a leap of faith while buying the AP. Can't be happier. I think the STI in the so called stage 1 is how it should come from the factory in the first place. It drives much smoother and I do feel a lot more power on the highway ramps, especially in the S# mode. I am disappointed though that it was not able to clear my TPMS light. Maybe a patch will come up in the future? Installation was super easy.

  3. Get it!

    By Dane November 10, 2014

    Totally worth it on all fronts! If you plan on keeping you WRX/STI for a long tim and plan on getting any mods for it make this your first stop. Only negative is the lack of an adequate manual, but other than that a 10/10!!

  4. Like Yo said, "no brainer"

    By Steve August 28, 2014

    Just installed and drove with 93 octane map. The linear response of the throttle is phenomenal. Power curve way better, just like the dyno readouts from COBB indicates. It is everything they say about the differences, too many to list. Yo and the people at COBB have been great to work with, enthusiasts with a passion for excellence...
