Specwar I came out of the Ford SVT world, Lightnings, Terminators, all supercharged and heavily modified. Custom tunes are the normal on those vehicles. 100+ RWHP gains through tuning is also the norm there.
Having knowledge of the why and hows, I just tuned my 08 JK with a Superchips Flashpaq. Basically I did it to change tire size to accomidate the 34.6" Yokahomas I have installed. However I have also altered a few other options which has improved the total "driveability" as JTPhoto JK refers to. Especially the shift pressure for the automatic.
If your looking for, and expecting instant power, its not for you, however if you want to improve overall driveability I would recommend it.
CIA's on a 3.8 would not be a wise investment, put your dollars elsewhere.
Just my $.02 worth.

I hear lots of speculation from those that don't own one. But, Each to his own. We own 3 Jeeps, 2 with the Superchips one without. There is a difference. Throttle response, transmission response, throttle while passing, other subtle little things. This not a seat of the pants Dyno and I will never say it has gobs more power, just better response and more enjoyable to drive.
A Superchips tuner on a 3.8 is the best bang for the buck mod for this engine and the only mod that makes a difference other then a supercharger or turbo. But it has to be fully utilized. Too many folks plug them in, set it to 87 economy and wander why it feels the same and why they instantly don't get 30mpg and an extra 100hp. However, if you choose to run 91-93 octane and tune for it, the Dyno charts do show higher torque numbers on the 3.8 then the 3.6.
You will find that people who have them and use them notice a difference in drive ability. Of course it also is used to set gears, tires etc and seconds as a trouble code reader.
A ProCal cost 1/2 the price but does half what the Superchips Flashpaq can.
8 out of 8 owners in our group are happy with the results.

michiganadam Do not get a cold air intake. At all. Performance gains will be minimal if at all. You will reduce offroad abilities for sure. The intake is specially designed for water crossings and is a great design i would leave it alone unless you get a snorkel....which will reduce horsepower but probably not noticably. Look at it closely, it gets air in the bottom and the engine sucks it out the top....Sure cold air is denser, but tight bends and excessive plumbing will kill the advantage. Not much room under a jk hood. Possibly find a way to help cold air get to the stock airbox....

Chips wont do much.

If you have an automatic and a 3.8, a regear would be helpful....theyre geared too high from the factory...

Racer8102 I've got a hypertech Max energy on my 2010 jkur, can't say that I noticed much power/ performance gain from it. I'm running the 87 octane tune. The benefits of being able toadjust shift points (automatic ) adjust for different gears an for the bigger tires, lock the rear locker in 2hi, an turn fan on/off an idle up for winching were thevmain reasons for the purchase. It may just be me, but it does seem to have a little more power down at lower rpms, but in no way anything like throwing a tuner on a deisel pickup an instantly having another 100 HP.

What are you looking to gain from a tune/chip is the question and will answer for yourself if you should get one.

Ruby Tuesday I have not used a tuner so I have no first hand experience, but from what I have read they don't do squat for performance or fuel economy. I'm sure others will say how great they are.

What Year? the 3.8 does benefit from a tuner, not sure about the 12-13 3.6..

DirtyTeddy I haven't chipped/tuned my JK, and I'm not sure if I'm going to YET.
My '08 Mustang GT is tuned and CAI, and that well..makes it a completely different animal.

As far as I know, chips/tunes help free up HP, crisper shift points (if auto) and a touchier throttle. CAI is cool if you have vehicle that demands lots of fresh air faster the better type. Wouldn't do squat for a Jeep.

I'll keep an eye on this thread to see what someone says who has done it to their Jeep.
