On the Diablosport Predator, you can adjust your boost, spark, and fuel in 1,000 RPM increments. This can be done with any stg computer (Ie, factory computer, Mopar stage 1,2,3 computer.
Multiple custom tunes.

Heres a Frequently Asked Questions (FAQ) compiled by S2ROT044 on srtforums.com.
What is the Predator?
The Predator is a hand-held flash programmer.
How does the Predator compare to the DTEC, SAFCII, Neo, etc.?
There is a fundamental difference between the Predator and the above tuning devices. Without getting into great detail, the above devices tune by altering the MAP voltage your PCM sees to 'trick' the PCM into a desired result (IE. boost, fuel, timing and so forth). These are, essentially, 'smart' or tuneable map clamps.
The Predator accomplishes the same thing, but more intelligently using an entirely different method. The Predator reflashes your PCM with your tune of choice and further allows you to adjust these tunes by altering boost, spark (timing), fuel and so forth from the hand-held unit.
Is the Predator hard to setup and use?
This may vary from person to person, but in my opinion, not at all. The Predator from the factory will come with a 'canned' 93 octane performance tune. When you connect your Predator to your car for the first time and go into the Performance menu, it'll first copy your current tune, which is most likely your factory PCM tune, to create a backup on the device. At that point, you can either modify the stock tune, or flash the PCM with the 93 octane tune. Before flashing any of the tunes, you can make adjustments to a number of parameters and also undo any changes at a later time if you'd like.
If you purchased the Diablosport Predator USB PC Update kit , you'll be able to connect the Predator to your PC to update the device with the latest .crom file(s), download/upload tunes, download and view logs and so forth. You can find all of this software here, on the DiabloSport website.
What can I expect with X modifications?
This is a rather pointless question and one this section sees a lot of. The real question should be: What tuning device is best for my needs? There are numerous devices on the market that are all capable of tuning your car. You should consider price, features, ease of use, support and other such things when making this decision. Ultimately, the power you make from your modifications will be a result of two major factors: 1. Your tune, and 2. The device with which you tune.
Depending on the available features/options for tuning, you may be limited (such as pulling fuel with a SAFCII, vs. altering fuel AND timing with a DTEC, or entirely reflashing your PCM with a Predator or the SCT xcal).
Which WGA is best for PCM controlled boost?
Another topic which has already been debated endlessly. Since there are already multiple threads on this, start out by reading over these two threads:
1. Stiff Wastsgates, Predator, and PCM Boost
2. Best WGA for the DSP
At this point in time, there is no specific WGA that has been proven to work better than any other. People have gotten just about every WGA on the market to work with their car. My suggestion is to start out with what you have and go from there. For example, I have a PTP WGA on my car. I will test with that first, then move back to my stock WGA, then perhaps a S2 WGA, then the FM WGA, etc. I feel that in the next few months, this particular issue will have much more data and be cleared up quite a bit.
Another thing to note about PCM controlled boost is the WGDC% set in your tune. Any of the canned tunes that come with your Predator are generally setup for the STOCK WGA. Therefore, if you have an aftermarket WGA with a stiffer spring, you'll more than likely run into issues if the WGDC% isn't set correctly. For stock turbo, bolt-on modified cars, this may not be a readily apparent problem, but can be as you raise the boost.
Will the Predator work with my X turbo setup?
The short answer is yes. However, if you're not running a stock turbo, you will need a custom tune. The tune will include things such as updating parameters to match your injectors, WGDC% for your WGA/boost and other such things to make your car run as smooth as possible without any bogging or excessively rich conditions.
Where can I get a custom tune, and how much does it cost?
You can make your own custom tune, however some Diablosport vendors can make a custom program for you.
How many tunes can the Predator hold?
The Predator can hold up to 5 custom tunes at one time.
To illustrate the ease of using the Predator on the 03-05 SRT4, here are some photos to show it being used.
Step 1: Connect the OBD connector to the OBD port under the dash.
Step 2: This is the main screen where you can choose to upload the performance flash, use the diagnostics feature to check engine trouble codes, and other features.
Step 3: This is the second screen youll get to after choosing performance tune. Here you can upload the 93 Octane flash, make your own performance flash, or upload your factory PCM flash back into your computer.
