True Flow XDI vs. HYPERTECH Max Energy ???
I would do exhaust and an intake or snorkel first (snorkel acts like a cold ram air and more functional). Then do the computer upgrades. With more air flowing through your engine the computer will show greater results over the stock setup.
Believe it or not the stock intake, exhaust manifold, and exhaust system (outside the can) all do pretty well. Replace them all with the greatest wiz bang stuff and you won't need to use your toes to count the horsepower gain with the stock PCM. The SC Flashpaq easily doubles that performance for a fraction of the price, plus will make better use of those other upgrades as you install them.
You will see more benefits of the Flashpaq with the Cold Air Intake than without it. So get the intake kit first, then the Flashpaq. We have Flashpaqs for sale for $300 in the vendors forum, and I will be running a special on some intakes.
Sorry, but that makes no sense. Lets say a CAI ends up doubling the additional power it makes when used in conjunction with a Flashpaq. Doubling 3-4 hp isn't close to the double digit hp gains you'll get with a Flashpaq and stock components.
I'm all about taking care of the bottlenecks throughout the system, but intake and exhaust bot have bottlenecks that there isn't easy remedy to. A CAI still needs to run through the stock throttle body and I'm unaware of a third party one for the JK or a programmer that currently addresses throttle body relearn. On the exhaust side of things, you still have the clunky Y pipe and cats. Sure you can get rid of them with a Borla long tube set of headers, but even Superchips says they don't work with long tubes. You also need to get some third party cats or you have a vehicle that isn't legal for on road use.
So as much as I would say that anyone is best off adressing all the things listed above, none of them are going to do as much for your vehicle as the Flashpaq. Best of all, when you start adding the other items in you'll get way more out of them than putting them on a stock vehicle.

I agree with Jpop. Every one of my family's vehicles have a programmer. 'Cept mine.
anyway....Dad's Avalanche and 2008 SRT8 Challenger both got intake and exhaust. Noticeable difference in sound, but butt dyno could only tell a little. Tuned Avalanche with Superchips and Challenger with Diablo (custom tuning). Wow! Huge difference.
Brother's 6.7L Cummins: Custom exhaust, DPF delete, EGR block, Intake...Wow! Lots louder and turbo sounds wicked! Install XRT 175 HP 250 lbs/ft of torque made all the difference... outruns new Mustang GTs and have beat Pontiac G8 GT.
So What I am getting at is that I am a first hand witness of using programmers and exhaust on all applications of vehicles and that although exhaust and intake are fun little mods that make cooler sound, the real difference in the seat of the pants is with a programmer.
I hope you enjoyed my story.

I do not have a superchips flashpaq, so I can't really help you decide. From the people who do have them that I've talked to (wildandwilling) they make a huge difference.
I do have experience with the Trueflow XDI intake and would strongly warn anyone who is considering purchasing. In my opinion and experience, it has a major design flaw that is a huge risk for your engine.
The way it is shaped in an inverted manner allows water to build up at the bottom of the tube, soak through the filter, and get sucked into your intake manifold or even engine. It was the main reason for my engine re-build.
For a street rig, it would be great, as I liked the sound and noticed some additional power. But if you go within a mile of mud or water on a trail, I'd avoid it like the plague.

This is my daily driver so water won't be an issue. In this part of Texas we only get about 20 inches of rain per year, so even less to worry about.
Thanks to all who commented. And I do believe i am going to follow JPop's opinion and start with the Flaspaq.
Unless I hear something otherwise in the next couple of days.
