I uploaded the new COBB Tuning Firmware Ford Update for my 2015 Automatic Transmission EB Mustang and can feel an improvement. The power seems to feel more lineal and the hard shift that was previously there from 1s to 2nd gear has smoothed out noticeably. Big improvement

 

Did you have another tune installed? I am considering a tune from another source other than Ford. Have there been any negative aspects of the Cobb Tune?

 

The Cobb Tune has been great, especially since the new Firmware update came out.

 

I recently purchased a 2015 ecoboost AT and installed a MBRP racing catback, COE Intercooler, the cooler spark plugs, and the cobb filter replacement. I first loaded the stage 1 map and didn't notice much difference. I then tried stage 2 and still noticed nothing. I added race gas to increase my fuel to 93 and loaded the stage 2 93 map and still nothing. My 0-60 is 6 seconds at best. In other forums they said I have to have the COBB intercooler and exhaust but I don't see how the system would know. I just cant figure out how I would be at 6 seconds with all these mods when a stock MT gets 5.5second. Any insight is greatly appreciated.

 

May 2015 AT ECO is 5.4 sec 0-60 with the stage 1 upgrade. Something must be eschew. Call Cobb, they were great to talk me through a couple of my questions. Good luck

 

for myself i have 2015 convertible with cobb stage 1 93 octane and stock i was running 6,7sec 0 to 60 and now with the tune im 6,0 sec maybe you have different gear ratio than the mt
