FAQ

What Is EFI Live Tuning?

EFI Live Tuning involves creating personalized engine maps for your vehicle. Instead of using pre-made tunes, custom tuning tailors the parameters (such as fuel delivery, timing, and boost) to your specific setup. Our custom tunes optimize efficiency , whether you’re aiming for more power, better fuel economy, or a balance between the two. We’ve got you covered!

How Do I Obtain Custom Tunes for My Vehicle?

Reach out! We will discuss your goals, modifications, and driving habits.

We will need basic information about your truck (VIN , any upgrades / modifications.)

Got a big turbo? Or large injectors? We will need you to record a datalog so we can revise & fine-tune the maps for you.

Don’t plan on modifying your vehicle more in the future? Bench flashing is the way to go! Ship us your ECM / TCM & save up to 50% off what it would cost for your own EFI Live device.

What Parameters Can Be Adjusted ?

Fuel Delivery: Optimize fuel quantity and timing for performance or efficiency.
Boost Levels: Adjust turbocharger boost pressure.
Torque Management: Modify torque limits for smoother acceleration.
Transmission Shift Points: Enhance shifting based on your driving style.

MISSION , VISION , VALUES , HISTORY

Mission: Imagine the excitement of owning your dream diesel truck, the kind that turns heads and thunders down the road. Now, picture the disappointment when a modification purchase from a so-called “reputable” seller turns out to be a scam. That’s the spark that ignited my passion and led me to create Piston Twistin LLC — a diesel performance business born from a desire to protect and serve the community with integrity and genuine care.

Vision: At Piston Twistin, we envision more than just a business; we’re building a sanctuary for motorheads. A place where the roar of engines and the smoke from tires bring us together to celebrate the art of automotive excellence. Our dream is to host an annual gathering that rivals the excitement of SEMA, where enthusiasts from all walks can share their passion and marvel at the mechanical masterpieces fellow enthusiasts have created.

Values: Respect is the engine that powers our interactions. We live by the golden rule: treat others as you wish to be treated. We believe in the wheel of karma — it always comes full circle, and we don’t take that lightly. To every single soul who has supported and followed our journey, know that your belief in us fuels our drive. We are here because of you, and we are eternally grateful.

History: Since my childhood, the allure of big trucks and fast cars has captivated my heart. I’ll never forget the earth-shaking moment when I first witnessed Grave Digger, the monster truck, in all its glory. The thunderous roar of the engines was intoxicating, and from that day, I was hooked. I also wanted to thank God for blessing me & helping me along my journey none of this would have been possible without him.
