2012--2016 GMC Acadia - 3.6L - Advantage

Prior to this tune I was considering trading in my 2015 Acadia SLT-1 AWD for an SUV with a V8 due to its poor acceleration and shifting.  With this tune, I can take advantage of higher octane so I use ACES IV Gasoline Formula to increase the octane of 87 pump gas.  Now, when I take off from a stop, I lose traction on dry asphalt if I accelerate too fast which activates the traction control.  Keep in mind that my Acadia is AWD!  The power/torque at low to mid-range RPMs is MUCH better.  Because of the added low-end torque, I recommend that one doesn’t use sport mode when driving on snow or ice…it’s just too much even with AWD.  I haven’t tried this tune without ACES IV octane booster but I assume this tune would still be great especially regarding the shift points.  Upon writing this I realized I should see how the tune performs without ACES IV.  I’ll update my review once done.  Also, my mpg has improved by about 2 mpg but I tend to take off quite fast now so it’s not an apples-to-apples comparison.  This tune exceeded my expectations.

I contacted Trifecta regarding a tune for my 2017 Acadia SLT AWD with LGX and inquired as to whether they could tune this platform as there wasn't anything listed on the site.

I knew they'd worked with the LGX and 6T70 trans separately in other platforms so I figured it wouldn't be a problem.  From what I understand this was the first tune for this engine trans combo they've done and were more than happy to give it a try as a "Beta" of sorts. 

The whole experience was totally painless and went smooth as silk. The PC software and cable interface worked beautifully and in no time I was up running. 

Low to mid-range torque is very noticeably improved. Top end power is improved and the extended rev range allows you to make better use of the top end power. When the engine is warmed up to operating temp the rev limit is increased in 2nd gear onwards to 7,000 rpm.

 I'm not sure what exactly they've done with the transmission controller tune but the shifts seem faster, firmer and gears are held longer giving it a sportier overall feel. 

My wife drives the Acadia daily and she hasn't complained about any drivability issues. When I jump in after not having driven the Acadia in awhile I instantly notice the sharpness of throttle inputs and improved performance. I drive all my vehicles hard it hasn't missed a beat. 

To sum it up, OEM tuning is like granny mode compared to the Trifecta tune! I highly recommend Trifecta Performance and this product is well worth the price. 

I've had this vehicle for over 5 years and have put 97,000 miles on it. I can't believe I waited this long to do this tune. Holy crap what a improvement! Like one of the other reviewers said, don't expect to be burning the tires off, this is a heavy beast of a vehicle and not a sports car. That being said I couldn't be happier with the tune. I need probably less then half of the throttle as before to get up to speed. It responds great and shifts nice. Having the ability to turn off the tune using the cruise control button is a nice feature. If you want to remember the difference, just turn on the cruise and try pulling out in heavy traffic. This is my second tune with Trifecta and both have been amazing. Next up is my Buick Regal GS.

Great tune. These guys are easy to work with and the process was simple. My 2012 GMC Acadia feels like a much lighter / smaller vehicle with a lot more power on the bottom end. Throttle response is much improved too without being overdone.

Thanks for a job well done!

This tune is awesome. I don't know if there is actually anymore horsepower or what they actually changed, but off the line the truck has way more pickup. I am running 89 octane, hopefully it would be even more responsive with higher octane for people that want to run that. For the price it is a great mod and easy to install.

Car has been totally transformed and driving enjoyment is very noticeable. For anyone contemplating this, do your homework and make sure your expectations are realistic.

The tune will not make your Acadia into a race car, or tire burning monster. It will remove all the sluggish slop in throttle response and jerky shifting and allow a very linear increase acceleration (very noticeable). Increase HP/TQ is very obvious, and makes the car feel more like a V8.

The way this car should of been from factory.
