I have been seeing a lot of questions lately among members about the various tuning options available for the Cruze. I'm creating this thread to aid those who are trying to make the decision of whether or not to tune their Cruze AND if they decide to tune it, which option they want to go with. If you wish to post in this thread, please only post about YOUR OWN experience with a particular tuning service or personal tuning experience.

In your post, please include the following information:

Vehicle Year, Make, Model, Trim
Engine Size with RPO code (if you know it)
Transmission Type (automatic/manual)
Vehicle Modifications (if any)
Name of Tuner/Tuning Software
Review of YOUR OWN experience with the Tuner/Tuning Software
Cost for Tuning
Dyno Sheet (If you have one) OR Screenshot of power numbers

I hope this thread is helpful.

Review of YOUR OWN experience with the Tuner/Tuning Software
Vince and Michael have provided me excellent customer service. I started corresponding with them fairly frequently in November of 2019. Aside from a weekend or holiday, the responses have been timely and they answered my odd questions as best as they could and they did not get frustrated with me as I tried to clarify what I was asking.

When I first drove the Cruze with the Trifecta Advantage (the "Stock" tune) I thought , this isn't bad, a little bit more according to the butt dyno. It was when I flipped the switch that things changed. I thought Wow!, I'm going to be getting more tickets I think.

I did have them change my speedo by 1mph to match the GPS speed readout on my radar detector so I wouldn't be speeding more than I wanted to. I am glad to have spent the money on this even though 80% of the time I run the stock tune.
I purchased my tune 0n 01DEC2019 but did not install it until 29JUN20 and haven't looked back since. It took me so long as I wanted to also document the car at the track as I went along. Remember this also entailed waiting for three tankful's of premium to change the stock fuel tables.

Cost for Tuning:
$398.00 for a 2011--2015 Chevrolet Cruze / 2016 Cruze Limited - 1.4L Turbo Elite
There is a cheaper tune for those who want to stay stock, it is $298.00

Trifecta tune
2012 eco 1.4L
Automatic

I was first just planning on getting their canned tune and not doing any upgrades. After the tune I wasn’t really satisfied and wanted more power. I paid the $180 to upgrade to their elite tune then got started on my mods. Downpipe, wastegate actuator, coil pack, and intake. Trifecta is great with their response times (usually a couple days). Don’t have dyno sheets but based off my MAF readings I peaked 185 whp or 220 at the crank. I asked for an aggressive tune but I’m not sure if that would change anything. My peak boost is 22 and it holds it all the way to redline.
If you can, I would post the calculations you used to get those numbers.

Not sure lol but you can look it up it’s a thing. It’s not always at 180 whp its the peak and the number changes at various rpms. Mine makes peak power at third and fourth gear then drops off.
These are a few posts from the internet:

Easy way to calculate HP? My MAF G/S is 382
So after a little bit of digging it turns out that G/S MAF measurement gives a relatively good HP Estimate
This is what I found on the net
N/A and Turbo Engine HP= MAF (g/s) * 1.25
Supercharged Engine HP=MAF (g/s) *1.1
N/A and Turbo Dynojet WHP manual= MAF (g/s) * 1.1
Supercharged Dynojet WHP manual =MAF (g/s) *0.95


Using the 1.1 ratio I get 420 hp flywheel hp or 362 at the wheels on Dynojet
wow just as my car stock hp rating

Please share your results!

MAF vs engine HP
I did analysis from my dyno puls vs logs and I got very consistent results with this math (this is average from many cars):

N/A and Turbo Engine HP= MAF (g/s) * 1.25
Supercharged Engine HP=MAF (g/s) *1.1

N/A and Turbo Dynojet WHP manual= MAF (g/s) * 1.1
Supercharged Dynojet WHP manual =MAF (g/s) *0.95
I have found that the #/min airflow is pretty telling. Take the value x 10 and its pretty close to what the flywheel HP would be. Not exact science, but it is in the ballpark.

Just to confirm, you only made 135 or so HP with trifecta tune? I have to be reading something wrong... On 8/31 graph.
I started at 109 on 87 octane - stock, then went to 119 on 93 octane stock to 135 on 93 octane with the Trifecta elite tune. So 135 -109 = 21 HP gain is not bad.

I can guarantee you my BNR tune makes more than that. No question. Butt dyno also confirms it.
Put your money where your mouth is! Let's see the sheets.

@Mr_Pat 's Cruze is DOA right now until he can resuscitate it.

That was two months ago!:unsure:
