When someone says the other tunes are better they usually mean you can get a bigger power boost than the Ford Racing Pro-Cal tune provides. For driveability the Pro-Cal tune is hard to beat. I've had it in my '13 for about a year now and really like the improved throttle response and additional low-end torque. The car just feels peppier and quicker than the +16 hp increase would suggest. On top of that I've picked up about 1-2 MPG better mileage in most driving. Since you have a 2011, if it's a manual, this tune also eliminates the annoying skip shift feature. Lastly, having the Ford dealer install it does not void your warranty.
The only potential downside is that you cannot use regular grade fuel at all, you're married to the 91+ stuff.
