Does anyone have the procal? I put a 3 inch lift with 35 inch tires on my 12 wrangler 6spd manual I have stock gears 3.21 and will be putting 4.88 in the future but right now money is a little tight.Now talking to a friend he said to get the procal it will help with the sluggishness is this true I read about it and it doesnt say anything about that just to correct the speedometer.Has anyone tried this and also do you just program it from your computer and plug it in?
the procal isn't a tuner. It might adjust shift points for larger tires if you have an automatic, but it isn't going to give you more power. It is a handy, low cost tool to be able to set variables, but it isn't all that flexible and the dip switches are pretty old school... Are we in the 80s?!
I actually returned mine and got a diablo trinity. It does everything that the procal does but is an actual tuner. I'm not sure which tuners are available for the 2012 model, so you might look around a little. The tuners are going to cost 3-4x more than a procal though.
As Gaucho say, Procal is highly versatile but not a tuner. You need a programmer of some sort to reset your powertrain control module (PCM) for tire size and your planned gear change. This will corrrect the shift points and dial in your speedometer. In my experience the performance returns from tuners isn't worth the money, but you may have a better experince.
Ups delivered my superchips flashcal today. And after unboxing, checking for an update on the computer. It took less than five minutes to adjust my tire size and the tire pressure setting. The 'digital' menu was very easy to navigate and a bonus function is the engine idle adjustment for winching.

Don't be offended but it blows my mind that people will plunk down big bucks for tires and a lift but not to regear. If money is tight, do the regear first and enjoy the hot rod performance until you save up for the lift and tires.
I'm not offended, but what blows my mind is that some people will lift their JKs and not know why, how or what constitutes a good lift.......
on topic....yes, use the ProCal or similar to reset for your tires so that speedo, odo and, if an auto, shift points are corrected. Why do a
half *** job and not finish it correctly for the price of a procal.....

I do not consider myself a smartass. I point out the obvious, search for the truth, and speak fluent sarcasm. I am, by experience, an accomplished curmudgeon.
I am gonna regear very very soon I just wanted to see if there is another option for the time being. And I have to find the right place to do it for me. I can pretty much do anything and everything on a motor or suspension but regearing scares the crap out of me
