🔥 **Remote Dyno Tuning this LS-swapped RX7!** 🔥

Got this RX7 on the dyno today sporting an **LS3 with a BTR RedHot cam** — definitely not your average rotary anymore. 😎

Remote tuning lets me dial in the calibration while the car is on the dyno, even when it’s hundreds of miles away. We’re working through the fueling, timing, drivability, and WOT calibration to get the combination running clean and making the most of that LS3/BTR setup.

There’s just something about an RX7 with a nasty cammed LS under the hood. 🔥

Need your GM LS/LT or Holley EFI combination remotely tuned? **Tuning by Jeff** can get you taken care of.

🔥 **REMOTE DYNO TUNING — ATLANTA, GA** 🔥

Got this **cammed 4.8L truck** dialed in remotely with **HP Tuners** for the guys at **Evolved Tuning in Atlanta, Georgia**. 💻🏁

Remote dyno tuning is a great option when you’ve got a capable shop on the other end. They handle the truck and dyno, I handle the calibration, and we work together in real time to get the combination running the way it should.

This little **4.8 with a cam** definitely sounds like it came to work! 😎

Big thanks to **Evolved Tuning** for trusting **Tuning by Jeff** with the calibration.

Whether it’s naturally aspirated, cammed, boosted, or a full build, remote tuning lets me work with shops and customers well outside the local area.

5.56 seconds. ⏱️🚀

That is how you clear a 60-130 mph pull in a hurry!

Check out this footage sent in from a customer running a remote calibration by Tuning By Jeff. This 1994 Mazda RX7 is rocking a twin-turbo setup, and to say it puts the power down efficiently is an understatement.

From rolling into the throttle at 40 mph to crossing the 130 mph mark, the acceleration is incredibly linear, smooth, and absolutely relentless. Dragy confirmed the data—a clean, violent, and stable 5.56s 60-130 mph pass.

When the hardware is built right and the remote data-logging process is executed perfectly, this is the kind of world-class performance you get on the street.

Huge thanks to BoostnFB for sharing the clip and trust in the calibration!

Another one dialed in and ready to hit the road course. 🏁

This C7 Corvette was remotely tuned using HP Tuners, and after working through the data logs and making the right adjustments, we got the calibration exactly where it needs to be. Remote tuning is all about communication, solid logs, and making precise changes until everything works together the way it should.

Now the car is running strong, responding cleanly, and is ready to stretch its legs on the road course where it belongs. Nothing better than helping someone get their setup right without the car ever leaving their garage.

Technology has definitely changed the tuning game — and when everything comes together like this, it’s pretty awesome to see.

🔥 Remote Dyno Tune – Alex’s Twin Turbo RX-7 🔥

Just wrapped up a remote dyno session on Alex’s nasty twin turbo RX-7 while he’s getting ready for Texas 2K.

This car is running an E40 ECU from a GTO with HP Tuners, and at first the car had us scratching our heads. It would pull hard but break up around 4600 RPM every time.

After digging into a few possibilities, we found the culprit: the original GTO coil packs were simply too weak for what this setup was asking of them.

We swapped in stronger coil packs… and the car woke right up. 💥

Final numbers:
💪 972 WHP
💪 799 WTQ

Safe to say Alex is now ready to go have some fun at Texas 2K.

Nothing like seeing a rotary chassis with a twin turbo LS combo making big power.

Let’s see what it does on the streets in Texas. 😎

Dialing In Power 🔧🔥

Spent some time today doing a remote dyno tune on a C6 Corvette for Evolved Tuning out of Atlanta. Technology makes it pretty wild — the car is on the dyno in another shop while we’re making real-time adjustments from miles away.

Watching the data, dialing in the fueling, timing, and airflow… then seeing the power come together on the dyno graph never gets old.

It’s a perfect example of how modern tuning has evolved. You don’t always have to be standing next to the car to get it running right — with the right tools, the right data, and good communication with the shop, you can make some serious power happen remotely.

Another Corvette leaving the dyno stronger than it arrived. 💪

🔥 Remote tune dialed in on this C6 Corvette at Evolved Tuning 🔥

Cold Air Intake + Full Exhaust = a whole new personality.
Crisp throttle, smoother power delivery, and that exhaust finally talks back the way it should 😈

Love how remote tuning lets us squeeze every bit of performance out of a combo like this without the car ever leaving the garage. Data-driven, clean, and street-ready.

If your Vette’s got bolt-ons and you’re leaving power on the table… we should fix that.
