I installed the base trifecta tune on my otherwise stock 2014 LTZ last January. Happy with it except the low speed drivebility is terrible.

Biggest complaint is while driving in the 35-40 mph range and someone in front slows down to turn. Let off the gas to slow down and roll into the throttle to accelerate, the car is very unpredicatble. Sometimes it doesn't react to the throttle as it should, other times it over reacts, a violent unnecessary downshift.

Thought this might be related to the hesitation problems so I've experimented with different plugs suggested here. Currently have the -8 NGK iridiums. But that doesn't seem to help any.


Any other trifecta tunes with similar experiences?

Which tune did you request when you made the purchase? Eco/Sport or Stock+/Sport? I went Eco/Sport at first and HATED the car in Eco. It was.... unpredictable. The unnecessary downshift went away after I had them switch the tune to Stock+/Sport. It works perfect now. The car is much MUCH more responsive and predictable.

I'm not sure now. I know i didn't get better mpg after install. My cruise control switch is always on, I'll try it off.

I was sure that the dual tune was more money when I purchased it nearly a year ago. I bought the cheapest tune they offered at the time since mine was all stock.

I know my 6M Eco since I have the tune installed seems a little easier to stall if driving in higher gears or not pushing in the clutch soon enough. Not sure of the direct link to the Tune or not, but an interesting observation!!!

I can't believe they are STILL doing it this way. I think they have their heads up their rears. I got rid of them for this reason and they couldn't fix it. I see the same complaints on Camaro, Cadillac, Buick, Sonic and other GM platforms they tune for. It's their signature feature I guess.

The OP is on old programming. The one you and others didn't like. This is not our newest revision of the calibration with the separate Driving modes.

Hey OP!

You are on older programming in which there were no selectable driving modes. The reason you are sort of lost as to what the rest of the guys are saying is because your calibration doesn't have that feature.

Please contact us to get the most latest version of your calibration in which the selectable driving modes are enabled. We will get you sorted out. Also, the small drivability quirks you mentioned are no longer an issue :)

That might be technically accurate. But why does this still pop up with new customers too? Someone needs to fire the 12yo that thinks a shotgun throttle control = mad power yo and keeps defaulting everyone to it.

I've said it a bunch. The select-a-tune was cool. Necessary even because the driveability was **** to deal with in power mode. You don't NEED a dual mode setup if someone used a little sanity with the pedal position and demand relationships.

Ok, so now I'm confused. I turned off the cruise control and it was a completely different car! This must mean I have the dual tune, right?

Is there an update to a tune that was purchased in early January 2015?

cncsparky. One thing that also wasn't mentioned here, is the fact that the original tune they send you, is just to put the tune on your car, and datalog for them to send you an update, so the tune is specific. It's just like a finger print. No 2 cars are the same. You can't just toss the tune on and run it. You absolutely have to datalog it and email the tune back for an update. When I originally got my very first tune, I was disappointed. I sent the datalog back, and it was magic. It was unbelievable. And I datalogged that tune, and sent it back, and it was even better than the second one. It's a must.

I've been wanting to do a tune on my gf's stock 2014 cruze 2lt with 21k miles but don't know where to start. I unfortunately do not have the place or tools to install this, So if I did get the tune, I would need to have my buddy or proffesional install it. I am not looking for more HP but I wanted to tune because I read it helped with the cruze's pesky turbo lag. Any suggestions or advice would be appreciated!!!

There isn't turbo lag. The turbo is starting to spool at 1500 rpm.

Run premium fuel and/or make sure your spark plugs are gapped right. If that doesn't work, change them to the iridium plugs others have recommended around the forum. Search for the "hesitation gone!" Thread.

I thought if you bought the lowest trifecta tune there is no data logging? So how would you get a car specific tune.
You still have to datalog and send back to have WOT check to make sure it is doing what it should when you do a few hard pulls and driveability. It doesn't matter if it is a select a tune or not and all tunes are designed for your specific car depending on mods you have done or none whatever the case may be.

Hey guys,

To clarify: our product is not a 'base tune'. It is a finalized calibration. If you buy the Advantage calibration product you are purchasing a tested and validated calibration and receiving the polished and final product. There should be no reason for data logging since your vehicle should be stock, 100%, if buying the Advantage package. It's all set and ready to go.

The ONLY time we ask Advantage customers to data log is if they are reporting some sort of MAJOR drivability issue. Which is rare and usually due to some mechanical part that's failing.
