Hey guys I am new to the forum and new to the Mustang gang. I have a 2011 V6 6-speed and was told it has a speed governor. I was told the top speed is only 114 MPH.......is that true? If so that sucks. I want to eventually do some modding.....tune, exhaust, suspension work, gearing and so on. So what I am wondering is, will a new tune delete the governor? I did a search and found no useful information.
Thanks for any information you all can give.

Normally you will have to manually input the removal of the speed limiter. It was very easy for me with the SCT tuner. Even a caveman can do it. I hit 125+ on a private road this month with much more speed availeable.

I xUOTE=heroic_bacon;7559571]is removing the limiter legal? what if you gotta go in for inspection?[/QUOTE]
It's not illegal to do it, the only problem comes if you have it under warranty and take it into the shop. They can tell when they hook it up to the computer, which will void the warranty. ...unless you turn the governor back on before you take it in then problem solved
I would be careful when removing the governor. If you do, I wouldn't personally go past 125. The driveshaft isnt meant to handle that kind of speed, hence the reason they put the governor on. There's a video of someone on YouTube that hit 130 I believe and he blew the driveshaft. I would just suggest that you replace the driveshaft with a stronger one if you want to hit higher speed like that.
I just found a few of those videos on youtube... Yikes! Yeah, definitely looks like you'd want to upgrade the driveshaft before giving in to any need for speed moments on a nice empty stretch in Mexico...
As far as I know the speed limiter should be set for the speed your tires are rated at. My 2013 came with tires with a "W" code which I believe is rated at 168 mph. That's where my speed limiter is set.
