🔥 THIS CHARGER CAME TO SING THIS MORNING! 🔥

We had the luxury of having this beautiful Charger jump on the dyno first thing this morning and sing the song of our people! 😂🇺🇸

And with the exhaust on this car… let’s just say it wasn’t just singing — it was putting on an opera! 🎶🔥

This customer has some changes he wants to make before we dive into a full tune, but he wanted to know exactly where he was starting from. So, we put it on the dyno and established a solid baseline before making any changes.

And that brings us to something we offer that’s perfect for anyone who has ever wondered:

“I wonder how much horsepower my vehicle actually makes?” 🤔💭

🏁 DYNO BASELINE — ONLY $100

For a simple $100, we can help eliminate that curiosity!

Your vehicle gets bolted on, run on the dyno, and we provide:

✅ Horsepower reading
✅ AFR (Air/Fuel Ratio) reading
✅ Converter efficiency reading

NO changes are made to the vehicle. This is simply a baseline so you know exactly where you’re starting.



💻 NEED A TUNE?

We’ve got you covered there too!

Our specialty in-house is Holley EFI, but we also utilize HP Tuners for:

🔧 Full custom tunes
🔧 AFM/DOD deletes
🔧 MDS deletes
🔧 Factory ECU tuning

AFM/DOD & MDS Deactivation — $50
(HP Tuners licensing credits are additional and are required for the vehicle.)

Complete Factory ECU Tunes — Starting at $700
(HP Tuners licensing credits are additional and are required for the vehicle as well as some systems needing specialty unlocking procedures.)

Holley EFI Tunes — Starting at $450
Pricing increases based on the complexity of your setup. (Nitrous, Turbo, Procharger, Ethanol/methanol)



We’ll be the first to admit it — we can’t possibly know EVERYTHING. There are simply too many platforms, systems, and vehicles out there.

But being in a rural market, one of our goals is to make sure you don’t have to travel hours away just to have access to quality equipment and tuning resources.

There are a LOT of platforms out there, and fortunately, we’ve found a couple tuners from our network who specialize in the platforms we aren’t as familiar with. That means when your vehicle falls outside our personal specialty, we have resources available to help get the job done right.

Sometimes all it takes is a simple remote connection, and we can work toward getting that perfect tune for your combination. 💻⚙️🔥

Whether you’re just curious about what your vehicle makes, need a simple system deactivation, or you’re ready for a complete custom tune…

BRING IT TO US. LET’S SEE WHAT IT CAN DO! 💪🔥

The Little Small Block That Could! 💪🏁

This one was a fun project!

The customer originally came to us for a dyno session, but we ran into a few issues right away—starter problems and a couple of oil leaks. After getting everything repaired, he brought the car back to us for a fresh set of headers, a custom exhaust routed under the car, and to get the carburetor and timing dialed in.

And did our guy Mark deliver!

With nothing more than careful tuning and minor adjustments, we picked up an impressive 80 horsepower from this little small block. Could it make even more? Absolutely. A little valvetrain work would likely wake it up even further and let the power extend further out, but as it sits, this is definitely the little engine that could.

The customer has no power adders and runs in a bracket class and told us he’s got a rival at his local track he’s been chasing. We have a feeling he’s going to be pretty excited the next time they line up. 👀

Whether you have a daily driver, a weekend cruiser, a street/strip build, or a full-blown alcohol drag car with a giant blower hanging off the front, we’ve got you covered.

✅ Hub Dyno Tuning
✅ Carburetor Tuning
✅ EFI Calibration (Holley & HP Tuners)
✅ Headers & Exhaust Fabrication
✅ Performance Parts & Upgrades

If you’re ready to unlock the power hiding in your combination, give us a call or send us a message. Let’s build something that’ll put a smile on your face every time you hit the throttle.

Today was another first—this Jeep finally got to open her lungs up a bit! 🔥

I know I’ve been pretty quiet lately, and I appreciate everyone’s patience. I’ve been focused on paramedic school (and probably will be for another year), but I want everyone to know that Moxi Performance is still here and continuing to provide tuning and performance services.

One of the biggest advantages we offer is our Mainline ProHub Hub Dyno. Unlike a traditional roller dyno, a hub dyno bolts directly to your vehicle’s hubs, eliminating tire slip and providing extremely accurate, repeatable data. It also allows us to safely tune high-horsepower, lifted, and off-road vehicles that can be difficult to strap down on a conventional chassis dyno.

We specialize in:
🔹 Holley EFI tuning (all platforms)
🔹 Select factory ECU tuning through HP Tuners
🔹 Custom performance tuning
🔹 AFM/DOD/MDS deletes (full parts deletes or programming only)
🔹 Drivability diagnostics and tune revisions
🔹 Performance parts and tires

We also keep race fuels on site:
⛽ 110 Octane
⛽ Ethanol (E85)
⛽ Methanol

Whether you’re building a street car, race car, truck, Jeep, or dedicated off-road rig, we’re here to help you get the most out of your setup.

📩 Send us a message or give us a call to schedule your next tune, dyno session, or performance upgrade.

Out with the old and in with the new!! Customer brought us a 1986 square body a couple weeks ago that was LS swapped for us to look at. Their initial install didn’t go as planned and they couldn’t get the vehicle running with wiring issues. Customer has been curious about Holley efi and the simplicity of it. After much discussion we got him a new Holley Terminator X to be swapped as well as a Painless wiring kit to clean up all the wiring throughout the truck to make everything work as it should. Customer will also get a new Holley fuel pump. Once this install is done we will get it dialed in on the dyno and back to the customer to enjoy.e

Congratulations to Mark on winning this weekend in Betty White!! Racing was close all weekend but nothing was as close as the finals for this race and it came down to reaction at the tree. Ole Betty was absolutely locked in. Thank you Mark for entrusting us with all your parts needs.

After doing a complete wire and install on a Holley sniper unit we had to let it sing. Some sniper units are only designed to control one system of nitrous as the inputs and outputs are pre configured. When I called Holley the gentleman I talked to was unsure himself if my idea would work for controlling a second kit but I was bound and determined to ensure this customer didn’t have to have a seperate controller for the second kit. Today that second kit got to add some power! Thank you Carson for trusting us and allowing us to do this install for you. Good luck this weekend!

Complete sniper install and wiring for nitrous. Time to get it dialed in on the dyno before the weekend.

Putting the boss lady to work today!!! Customer brought us a vehicle to tune and it’s not running right. Found two dead cylinders, one being a coil and the other being an internal issue. She’s learning to do compression testing!
