My Trifecta Tune & a Question or Two....

After considering both the Overkill and Trifecta Tune, I ended up going with the Trifecta. While it was a fairly easy process, there were a few steps that you kind of have to figure out on your own. Overall though, it only took around 15 minutes to install once everything was available.

When you order it, you get your "tune" as an email file (download it first before you start your tune I later learned) and then your Tuner Cable comes a few days later. Most PCs have just random USB Ports so make sure that you're actually plugging the cable into a true USB Port and not just a "Charging Only" one, because it will give you an "Unrecognized" Error which I initially thought meant there was something wrong with the cable itself.

Driving the car after the tune was installed was like driving a completely different car. As one reviewer put it, it felt "lively" and immediately responsive versus the previous feeling of having to wait for the motor to react one you hit the throttle. It's also louder in the intake sound which I really enjoy as well. It is well worth the money and I'd use Trifecta again for any car that I had.

So now I'm ready for the next stage of upgrades. Has anyone installed the Overkill Simple Intake & 80mm Throttle Body with a Trifecta tune? If so, will it throw a code? Or is not really worth getting the Intake and I should just go with the 80mm Throttle Body and a drop-in K&N Air Filter?

I'm also planning on adding the JacFab Intake Spacer and (if it seems to also make sense), the Ported Intake. As far as I can see, that seems about it for these cars as I haven't found anything regarding Cams, etc and I've yet to hear an aftermarket 3.6L exhaust sound anything but raspy.

Any feedback would be appreciated. Thank you!

Any modifications to the car would require a retune. Otherwise the aif/fuel ratio will be messed up and may actually lead to a decrease in power and response. Trifecta does offer Advantage+ and Elite version of the tune, not sure which you purchased. I only have the standard tune here as I only have stock parts but from what I gather if you have either the Advantage or Elite you can data log and send them the results and they will do a custom tune. You would have to contact them for more info than that.

Yes absolutely. The biggest difference will be the responsiveness of the gas pedal. I cannot speak of any fuel benefits as I do not track it. Any horsepower gains are minimal but the responsiveness of the pedal will easily make it feel more sporty.

It was very easy but you will need a fairly current laptop or surface tablet with usb to do it. Check the requirements on the site. https://www.trifectaperformance.com/...er-guide.html/

I think the Horsepower increase with the Trifecta Tune is more than just minimal. Trifecta says on their Web Site that you can: " . . yield gains of up to +14 ft-lbs and +20 WHP under the curve (and +14 ft-lbs and +16 WHP peak on 91 octane) to a completely stock Chevrolet Impala 3.6L (LFX) MY2014+. " To me, it feels like every bit of that power increase is there. I've used numerous tuners on numerous cars and the Trifecta Tune has been the first or second best one I've done as far as performance gains.

And as I said earlier, it's more than just a Power upgrade, it's a drivability upgrade. throttle response is almost instantaneous and gear shifts are crisper and quicker. As my first mod to my first Impala, it inspired me to do a lot more with the car to see what I could get out of it. I've since added the JacFab Intake Spacer, a K&N Drop-in Filter and replaced the stock Y-Pipe (the muffler shop I had to do it said the factory setup was the least efficient and most power-robbing design they had ever seen) with a larger, free-flowing and straight-direct Y-Pipe. I've only had those two mods on a for a few days so it's hard to judge them yet, but they definitely feel like they're adding even more oomph to the car's power band.

This is my first Impala and I'm really having fun with it. I plan on adding the 80mm Throttle Body and Simple Intake from Overkill later this summer. I read somewhere that these cars really respond to their upgrades, and I'm a firm believer in that. I raced a friend's stock '17 Impala LT V6 and beat it by almost 2 car lengths and was still pulling away at the end. Good times..........
