CMD or PowerX

Ok guys I have the auto trans as we all know.

Which one do you guys think is better. I wanna stay around 250 ft/lbs of torque since the 2.0T automatic transmission is rated at 250.

When my lease is up I will probably trade up to the 3.8 and do some serious things to it, but I think on this car I will be satisfied with marginal HP gains since the stock trans can't handle it unless I rebuild for 4 grand. I will probably just get a piggyback, intake, and maybe an exhaust. And would it be wise to get larger injectors with either of them?


So which one guys!

Thanks!

better? PowerX. the CMD only controls fuel, ignition, and boost. the PowerX has full control, including cams, the rev limiter, among other things.

it's also more expensive in the long run, as you need to get it tuned at a shop each time you want a different map. if you're not planning on much modding, a single reflash will probably do what you want. the generic reflash + module is only about $650, but BR has a stage 1 kit that includes an intake and a custom map for $850.

The custom map might be nice. You know how it has 3 options. If you do the 3rd one does it still eliminate the rev and speed limiter?

Also the BR reflash produces 290 ft/lbs of torque so I don't know if that would jeopardize my AT.

But someone posted saying that the AT is way less responsive to a piggyback/reflash so it might not be that bad.

I prefer the PowerX, but with the downfall is the module is then married to your vehicle & can't be resold when you trade up to the 3.8L. With that said & the minimal power you are shooting for, you might be better off with the CMD in this scenario.

^ i believe if you call PA when you sell the car and have some proof they'll unlock the module.

ahh, good post this is what i was gonna ask next month. But the only thing with the CMD is your doing all the mapping and etc. your self which leaves me scared i might mess something up. Those of you that have the CMD, how easy is it on a scale of 1 to 10, and did i understand right when Tufast said that it does not need to be attached to the car everyday?

Now that would be nice, but what if you currently have module installed on 2.0t & are purchasing 3.8L, will same module work on different engine?

i dont think that the same module would work going from the 2.0 to the 3.8. but i could be wrong

I agree & don't think it would swap from one engine to the other.

No need to "do everything yourself" as any capable shop should be able to tune with CMD. If they can't figure it out in 10 minutes then they're not worth using, as it only took me about 5 mintues to get used to it. If you don't plan on getting any custom tuning done and only plan on using an intake then I would suggest the PA reflash, as the generic CMD tunes run pretty rich on the automatic my wife has. Most of the PA reflash a/f ratios I've seen have been in the 12:1-13:1 range so perhaps they won't run as rich as CMD canned tunes do on the automatic. The 12:1-13:1 is also a little scary to see people running, but I'm sure PA knows what they're doing and deemed that a safe a/f.

With that said, the cost of a custom tune with CMD or just a generic PA flash should be about the same. At the levels you're talking about, adjusting timing, cvvt, etc isn't really an issue. I highly doubt there are that many parameters altered in the generic PA tune, there's just no need. The stock turbo is going to max out around 250 for everyone regardless of timing or any other ECU tweaks.

PA is a much simpler solution to use but you're stuck with their tune... If you are going to order one I would suggest using Beyond Redline as they have the most experience with the PowerAxel unit.
