      2015 EcoBoost - EverettC

      Great buy

      Bought this expecting a quick and easy way to gain extra hp/tq and also have a code scanner, and i was not disappointed. Very easy to use, understand, and is very useful when it comes to diagnostics. Currently running the stage 1 93 tune, but plan to move on to stage 2 very soon. Overall, 5/5!

      2021 EcoBoost - StockExhaust

      Works like a Champ

      Easy to install and configure, change the program on the fly, all in all amazing. I told my son about it and he bought one as well!

      2015 EcoBoost - ChanceyC

      A must have for the ecoboost

      Easy install, comes with everything you'd need. Good bang for your buck in terms of power gains. Feels like I'm driving a completely different car paired with CAI intake and CVF Street intercooler.

      2015 EcoBoost - VoodooChile

      Ecoboost Necessity!

      Loads of built in aids and features. Built in tunes great for common bolt ons. Boost peaks reading 24lbs and very noticeable. Added bonus shows gear you are in all the time with 6R80.

      2018 EcoBoost - CrimsonKilnm

      Great deal!

      This was a "used" item and it works great! It maxed out my mods with the Stage 2 93 tune and even increased my mpg in the process. I have CVF catted downpipe and intercooler w/chargepipes, resonator delete with NXT axleback mufflers, Airraid tube with k&N drop in filter, catchcan, fastbits diverter valve. The lag disappeared and my turbospool sounds amazing.

      Cobb Accessport makes it feel like a new car

      Works perfectly. I got mine as an open box item for half the price and it worked like new. It came with all the OTS tunes, but I used it to get a pro-tune and it was well worth the cost. Really wakes up the Ecoboost. If you want to have more fun with your car and love it even more then install the Cobb Accessport. Who needs a warranty anyways?

      Cobb Accessport

      First off let me get this out of the way: there IS a noticeable difference between bone stock and the Stage 1 (in my case 93) tune. I did a light pull with maybe 80% throttle and my HP & TQ went up to about 333 and 392 respectively. All I currently have on the car is a Roush CAI. Where the accessport really shows its worth (which for the price is a bargain) is with other supporting mods. If you are like me, and you plan to go FBO with maybe an NX2 turbo kit or something like that, this is a must have. If you’re on the fence; just buy it already. You’ll thank me later. A slightly more in-depth account of the stage 1 tune: Power gains are way more noticeable in the low and especially mid-rev range. The throttle responds better, the car launches better, and overall feels a lot more torque-y. Second gear feels COMPLETELY different, and third gear feels even better than it already did (this is for the 10r80 transmission btw). Also, my motor seems to be running better. I have gained about 2mpg and when cruising at 90 on the highway, the engine temp barely goes above idle. Actually, with the hot 100 degree weather in the tri-state area right now, I’m rather impressed.
