Ok hearing this might be a good idea. Just lifted my jeep 3.5 rockKrawler and went from 33 to 35's. Having some issues with traction control and ESP but need to straighten the steering wheel and I am told that wills top it. IS this device something I should look into?

 

that is true. Make sure that your axle is centered and your steering wheel is centered and the ESP issues should die.

 

There is a lot written about the AEV ProCal here for sure. It works and it is something to consider.

The Procal would probably be good for you. You can correct for the tire size change, which will help with the tranny and the ESP. In addition, it has a feature to help re-center the steering wheel. Mine definitely improved the tranny shift point issue by correcting for bigger tires (which also got my speedo correct), and I haven't had the ESP go off on a tight corner since using it.

 

Do you have the 6-speed or the auto? With an auto it will probably be a good investment, depending on your needs, cause it resets your shift points. I have the 6-speed w/o TPMS and couldn't justify it, however I also got the dealer to recalibrate the speedo free of charge and I re-centered the wheel when I lifted it so I never had esp problems. To try an save some coin I'd check an see if your dealer will recal the speedo for you. I believe there are write up's on here about re-centering your wheel. Not to smash aev but if I was going for a programmer for an auto I'd probably go with a superchips/hypertech (idk who makes em) to get max performance for towing/gas milage/speed ect.
