Best 4.0 Tuner Programmer

I'm looking for some info on programmers for my 04.

A new cam and a few other performance mods (stroker) are likely for the future so I would like to have a plan to keep the AFR in spec for when the time comes.


I've seen hypertec and superchips etc, are they any good? I've heard good things about the split second tuner as well.

All opinions welcome

I just put the EDGE chip and throttle body on my jeep. I love the turnout. Definitely made a huge difference.

Chips, cold air intake, throttle body spacers, all just a waste of money (snake oil). If you want improvement do a regear, do an engine swap, or buy a new car. These 2.5/4.0L engine are not meant to be tuned, they were put in Jeeps for their good low end torque offroad, not to red light race.

the only chips that will accommodate the mods you speak of are the Unichip and the SplitSecond FTC-1. Both are piggyback's. The FTC-1 is a splice and cut wire type & comes with its own MAP sensor. The Unichip is a plug-n-play tuner. Both must be tuned via a dyno shop for your specific mods. All other chips are a complete waste of money and cannot be tuned for a custom engine setup.

I mad my own map sensor adjuster. I dont know if you can with yours being a 06. It cost me 15 bucks and works! You will need a Air/Fuel gauge to tune it though.

That's what I was thinking, thanks.

Until you do build a stroker, it's all a waste of money.

Even when you have a stroker, if you don't have the right gears you'll never be putting down the power and torque at the time you need it.

What tire size to you run/plan on running?

The Original poster asked about tuning a Modified Cam / Stroker. You replied with the Same old BS about about CAIs, chips and spacers on Stock engines.

No, the OP asked about tuner chips, I gave my opinion. Most plug in chips are a load of crap, but as Unlimited04 there are some real chips that are good, but require dyno tuning.

Specifically the OP gave the name "Superchip" which is one of those crappy one that don't do anything.
