New to all this and im needing little help in trying to get little more giddy up and gas mileage. Give me any suggestions they will be greatly appreciated. Thanks

 

The AEV ProCal will let you adjust your tire size and gear ratios, but I believe no programmer has cracked the code for the 2011 to date to tune the engine

 

The 2011 has not been cracked, so the only option for tuning is to replace the computer with one from a 2007-2010.

 

well i was told there was something out there that plugs in under the gas pedal that would help???

 

The AEV ProCal plugs into the OBDII port which is below the steering wheel / above the pedal assembly. That's your lone option for the 2011 save for replacing the ECU.

 

You're talking about the Sprint Booster. It says that it works on '11???

can someone explain the aev procal system??? im very interested.... really want to know how it changes gear ratios

 

It doesn't change gear ratios. It adjusts computer settings to compensate for changes you have made to your vehicle. For example... if you go to larger tires, you can input the new settings into the module which will then adjust shift points (in an automatic transmission) and the speedometer to compensate for the increased size of the tires. By design, it re-calibrates things.

 

I installed a SprintBooster and a Procal on my 2011 and feel that they are some of the best additions I have done. Although the SprintBooster is certainly not cheap, the increased throttle sensitivity does make the Jeep feel much more peppy and fun to drive. The Procal got the auto trans shifting back in order, so I no longer have to shove my foot through the floor when passing.

I am only running 33s with 4:10 gears, but the combination of these 2 made a significant improvement in drivability. For me, they have been worth every penny.
