2012--2020 Chevrolet Sonic - 1.4L Turbo Elite

Outstanding tune!  It really woke up my ride (2013 Sonic RS) and worked great with my other installed mods.  Amazing customer service as well.

Trifecta team and support are absolutely amazing. fast responses and great product. very knowledgeable team!. i currently have a 2018 sonic rs with all bolt ons, zzp turbo, bigger throttle body, e85 flex fuel, bigger injectors and so on...… and trifecta is supporting this car 200% car runs great and pulls very hard for being a 1.4l Anyways when my car was stock and just tuned from them there is a huge difference as well!!! so if you want some more good useable power and don't want to mod your car i also highly recommend it!!!!

I bought this tune as a gift for my girlfriend and it has been nothing short of perfect. She absolutely loved the tune, noticed an immediate increase in power and overall performance, and overall just makes the car more drivable. 100/10 phenomenal product and amazing support.

I purchased this tune on December 27th. It was part of Trifecta's Black Friday sale. It was $348 for the Elite compared to $498. I received the EZ Flash Cable in the mail on December 2nd! Connected the Cable to my Mac (Running Windows 10) and via a USB-C Adapter. A Video is included in the EZ Flash Cable Guide, which shows you the program in action, and instructs you on how to put your vehicle in Permanent Accessory mode (for those with Push Button Ignitions). Once I sent them a screenshot of my ECM Security Code, and VIN for Verification, I received my Tune Calibration in literally 5hrs. Once I received the TRX file (File that is flashed to the vehicle) I connected the vehicle again, and Initiated the Programming. From start to end, it took roughly 10mins. When it's completed, I turned the car off, disconnected the cables, and started the car. I took the car for a drive. 

I AM TELLING YOU, THE CAR SHIFTS SMOOTHER, SHIFTS FASTER, and When Cruising, I've been seeing MPG improvements UP TO 20% Better! The Shifts are Aggressive! I can pretty much maintain speed with a Mustang GT 5.0 (The Sonic is roughly 600lbs lighter.) I'm lightning quick off the line from a light! I've been finding any excuse to drive it! This is how the car should have came from the factory. Worth every penny! This Tune in Combination with a ZZP Cold Air Intake, literally gives you the feeling of owning a brand new car for under $600 combined. If you purchase the Elite Tune, you get free of charge calibrations for any added mods after the time of Purchase!

GO TRIFECTA!

i was really skeptic about a tune for my sonic i made the purchase with a quit few concerns but srsly now ... its literally realese the beast.

still 4 cyl 1.4 engine yea? proportions ...

fuel economy aspect- 

still no change for me, it still same a it was before. i would give it a bit more time since i am in quarantine here so the travels are very low.

gear aspect -

the gears change are more aggresive, no more kick downs for intermediate circumferences, just a little go on the gas.

power aspect-

you can feel the change rite after the install, it feels like you allways have an avalible power when ever you need, its really nice. 

you can even feel the power at 6th gear on 110-125 km/h unlike before.

i recommend on trifecta not just because the tune but also because their customers service wich allways there for you, and im not over reacting or bot.

goodluck!

Awesome company! Always helpful and quick with responses A+ customer support will continue to use and recommend from here forward! 

I read all of the previous reviews and forums on this tune before I bought it and I have to say it was well worth it. If you want a way to make the sonic come to life and make it even more fun to drive then this is what you need. The difference is night and day. It’s hard to read the reviews and trust what people are saying but I’m telling you everything that everyone has said about this tune is true and as long as you follow the instructions right then it’s as easy as a click to install. I also tinkered around with the flash tool and I love the other features that it offers. I would highly suggest to get the elite package if your tuning that way you can get updates with all of the upgrades you install. I appreciate the high level of customer service with their quick responses to questions and the work that the programmers put in to make this possible. Great job Trifecta team!

I purchased the Elite Tune for my 2019 Sonic 1.4T Hatch. With my mods and this tune, the car is unrecognizable. Quick response to get initial tune after my unlock code was sent. 

I bought this for my 2015 sonic turbo and went ahead and got the elite package. This is a great product and just the new tune from stock setting was a fairly big inprovement! The biggest thing that I have loved is that as im slowly building the car I can have it always up to date on its tunes. The elite package is definatly worth the money i would recomend it if you plan on doing any modifications to the motor or exhaust in the future.  I dont have a single complaint and trifecta has far exceeded my expectations!

Outstanding tune and amazing customer service. I couldn't have asked for a better company to order this astonishing tune from. 

Best bang for your buck!

I am a commuter that drives 120 miles round-trip per day. I drive a 2013 Chevy Sonic sedan with the trifecta elite package. I can now get 40 plus miles per gallon with my 6 speed manual, and as important I know have passing power that was missing stock. Love this tune and the service I have got from trifecta when I had an issue with my car. They helped figure out through their software that I needed to replace the pcv that was built in my valve cover. Couldn't ask for more.

I love the tune. It makes the car fun to drive.

For starters I'm in Denver so my elevation it's 5000+ get all the time.

This tune is a night and day difference, and really opens 6th gear up at lower speeds for practical use.

The engine has a fairly narrow power band so, the tune isn't going to fix that. Once you're in the power it pulls like a different car altogether.

The gas mileage will tend to go way way down, this is to be expected if you actually use it though. If you drive light you can still get close to stock mileage.

I wish the driving mode selection was more like the one Cobb uses for other cars.

My only real gripe about this tune is it goes into the body a little quickly, the slightest use of the gas pedal can put you way into it, so it really means you gave to use eco mode a lot of you don't want to constantly be on the boost. Having a more gradual or adjustable feel to the throttle would be nice.

Amazing difference... Kudos to Trifecta for the easiest 1.4T 93 / E85 performance option!!!

I received two performance programs for my Sonic RS, One for use on 93 Octane, and one for use on E85. I can't believe the difference. I did install 42# Bosch injectors (very quick and easy BTW), and loaded the 93 program. The power with the performance flash is remarkable. I do notice that when I change programs (using the cruise on / off button on my steering wheel), it takes 5-10 seconds for the program to shift - I didn't realize there would be a delay when changing, but no big deal.

This morning I filled up on E85 and installed the program flash for the higher octane. Again, a boost in power. I see that I'll have to get very used to this upgrade as I very much feel the traction control cutting power when accelerating quickly. I love that Trifecta was able to provide me two programs however that I can toggle back and forth to tell the ECM / TCM what type of fuel is in the tank and how to perform. This allowed me to totally bypass the installation of an ethanol sensor that would tell the ECM what mix to run at. Of course I need to either run E85 or 93, but so be it... not that difficult.

Superb results Trifecta to turn my 138 HP Stock RS into what I'm guesstimating is close 190 HP at a cost much lower that I would have paid with other E85 ready options.

PROS TO MY SOLUTION:

Power is amazing

Easy to Install

No ethanol sensor needed

Great cost by comparison

CONS TO MY SOLUTION:

Cost to continually replace tires - LOL

There will be a long preface to this review explaining why I can't give the tune 5 stars. See TL:DR below.

I live in Denver and for anyone who hasn't driven a car at high altitudes, it is a major annoyance. A car that feels quick at sea level will feel sluggish up here. It is a MAJOR difference and for naturally aspirated engines can mean up to a 2.2 second difference in the quarter mile. Turbocharged cars can help eliminate this difference by making up for the lack of atmospheric pressure with additional boost from the turbocharger. The Sonic has this function from the factory to help the car make similar power levels at different altitudes so the turbo is already pushing more pressure than it would at sea level. The tune was not the mind blowing power difference I was hoping for and I can understand that the turbo can only be spun so fast until reliability issues would creep in.

However, the tune definitely woke the car up big time, especially at partial throttle and the overall throttle response is excellent. Even in 'factory' mode, the car is a lot more fun to drive. The issue I seem to be having is just with consistency in 'tuned' mode and I think it just comes down to altitude and the inter cooler suffering from heat soak.

TL:DR: At low altitudes, this tune would turn your Sonic into a mini monster. At high altitudes it is a worthwhile upgrade that offers good bang for the buck.

"As advertised" for my 2014 Sonic LT Hatch. From the new stock calibration to the performance calibration, this tune is very effective and highly refined. The stock setting is vastly improved over the 2014 MY OEM calibration, with more linear power delivery, virtually no intrusion of the OEM transmission control logic (are the clutches applied? let's see...), better idle quality, and smoother garage shifting (P-R-D-R-P). The switching to performance via the cruise control master switch brings the powertrain instantly alive from a standstill all the way through extra-legal highway speeds. The throttle response and shifting are crisp, while the refinement remains. It works extremely well with the K&N Typhoon CAI I installed. Rolling anti-lag in moderate city traffic makes for an effortless commute. Fuel economy is improved. The ability to go stock in the low-speed stop & go and switch to something more is a great feature. While it's not quite as fun as my 2013 Boxster S, it's made this little commuter car far more pleasurable to drive. Outstanding. Looking forward to a similarly effective tune for our company's 2016 Colorado 2.5L work truck.
