Just wondering if anyone knows. Would be nice to see some parts that are recommended by the manufacturer, like the similar cars with the same engine have available. I understand that wasnt the end goal in the design but it would be nice to add a little pep for enthusiasts. Maybe with the redline release lol

I did not see anything from Chevy for the Trax as far as performance.
I will be turning to Trifecta at some point as the Encore folks seem to enjoy the end results.

The Trifecta website does list the Trax, very interesting. Anyone use it yet? Will it still pass Calif smog tests with this mod? What about warranty issues? I'm old school as far as performance improvements and have never gone the software route before.

The Trax has pretty much the same engine as the Sonic which I own. My Sonic has the Trifecta tune. I am past warranty on the Sonic but is my understanding this goes in a transparent mode.
I can't say if the dealer sees it or not. I had my Sonic since 5500 miles and in for service on several occasions and they never said one word about a "tune".
I can tell you though that it adds a good bit of get up and go. SO I will be tuning the Trax at about 1500 miles.
I have tuned a good many cars using Trifecta software and IPF.
Either way is a good choice, at least has been for me.
I read over on the Encore forums of some that have put the tunes into their vehicles and enjoyed it.

Good to know thanks for all the info guys. I was eyeing up the trifecta and it looked like under the hood it was almost the same setup as a sonic like you said. Any thoughts on trying to get a sonic cold air in there till we get some more options?

I may go to the parts store and buy a couple Spectre pieces just to replace the rubber tube between air box and turbo.
Those have been prone to fail on the Sonics and I am guessing there is no difference in them materials wise.
I used a DDM works intake on my Sonic but will not work on the Trax.

Never used Diablo. If you search around on the Sonic forums may give you a better Idea. Trifecta has worked well for me and is really easy to do. You can revert quite quickly if needed as well.

Trifecta told me the site for Trax was going under construction but the info for Sonic was pretty much the same.
I haven't ordered yet but they will calibrate for completely stock and then you can run 87-93 octane with 91 or higher giving you the best performance.
There are not many aftermarket performance parts for Trax on the web but you could easily make up a CAI for it.
I will leave the exhaust stock as I don't want it any louder as my wife drives it mostly.
So the way I read the power gains around 44WHP and 51 Ft lbs tq. Are gained
I think these are peak gains using premium fuel(93)
As far as filling out the form I would fill out each line with the required info and where it says intake I would put stock as well as exhaust stock.
No ethanol calibration needed as this would require larger injectors and running E85 which I am guessing you are not.
For select a tune choose cruise button.
For No lift shift select NO as this requires manual transmission.
The select a tune by turning on and off the cruise button is a great way to go from stock to tuned at a flip of the switch. Kinda cool.
You can submit an inquiry form and they should be able to answer most questions for you.
You will need a laptop with Windows 7 or newer to install your tune.
it will seem kinda scary the first time, but I have tuned many for family and friends and it is like brushing my teeth now.
Even my son after tuning his first time said this is way easy.:D

I may have to look into the Trifecta, I have a Diablosport for my Silverado and am very happy with it, Diablosport also makes a tune for the Trax. Since I already have the hardware I can add the Trax for $149. to use the same tuner for both vehicles. I have the LS version of the Trax so I do not have a cruise switch to switch between tunes.

Looking forward to hearing some feedback about that tune once you get it done.

Could turn out to be standard practice among a wide range of owners here in the future.

They tell me that you don't need the cruise button. I will have mine written without the select a tune feature. Meaning tune is active all the time.
I just think it makes the car what it should have been from the factory.
My Sonic has it set up to be active all the time and it drives no different other than the go pedal is more fun.:D

Working out a couple of things and when I get it installed will do a before and after video for you guys. I will take video of the speedo for comparison.

Hang tight will be pretty quick.
