Custom In-House Calibration by Piston Twistin

This product is for customers who want one custom EFI Live tune file of their choice, professionally calibrated for their exact setup — no add-ons, no hourly fees, no surprise charges. Lifetime Unlimited Support.

If you already own an EFI Live AutoCal or FlashScan (any generation), this is the simplest and most cost-effective way to get your LB7 Duramax EFI Live tuning done correctly.


🔒 IMPORTANT — PLEASE READ BEFORE PURCHASING

  • This is ONE single EFI Live tune file

  • NOT DSP5 / NOT Switch-On-The-Fly

  • ✅ You must already own an EFI Live AutoCal or FlashScan

  • Any generation EFI Live device is supported

👉 If you are looking for multiple power levels or DSP5 switching, please select our LB7 DSP5 SOTF EFI Live Tuning product instead.


Why Piston Twistin EFI Live Tuning Is Different

At Piston Twistin, we believe customers should not be penalized for upgrading their truck.

Many tuning companies advertise a low base price, then charge additional fees for:

  • Aftermarket turbos

  • Larger injectors

  • High-flow or stroker CP3 injection pumps

  • Tuning support billed hourly

Those costs can quickly add hundreds of dollars beyond the original price.

We don’t do that.


✅ Our Pricing Philosophy

  • One flat price

  • Any turbo

  • Any injector size

  • Any CP3

  • Unlimited tune revisions included

  • No hourly support fees — ever

Your truck evolves.
Your tune support shouldn’t stop when the clock runs out.


🔧 What You’re Getting

✅ Fully Custom EFI Live Calibration

Every tune is built 100% in-house and tailored specifically to:

  • Your truck’s modifications

  • Your intended use (daily driving, towing, street performance)

  • Safe, repeatable, reliable power delivery

We start with a proven base calibration, then have you perform a full-throttle datalog. That data allows us to fine-tune fueling, timing, torque delivery, and drivability specifically for your truck — not a generic file.


⚡ Improved Throttle Response & Torque

  • Faster turbo response

  • Smoother power delivery

  • Strong low-RPM torque

Perfect for daily driving, heavy work use, or aggressive performance setups.


⛽ Optimized Fuel Efficiency

When driven responsibly, properly calibrated EFI Live LB7 tuning often results in:

  • Improved MPG

  • Cleaner combustion

  • Reduced unnecessary fuel usage


🚛 Towing & Work-Ready Performance

Whether you’re towing heavy or just want stable, predictable power:

  • Safe EGT management

  • Strong mid-range torque

  • Smooth drivability under load


🔄 Stock-Friendly & Reversible

  • No permanent modifications

  • Return to stock at any time

  • OEM-safe logic retained where appropriate

This is a wonderful sheepskin
Size: 2' x 3' (Sheepskin shape), Color: Creamy White
This sheepskin is so soft and comfortable. I use it on my couch and it really helped me stay warm in the winter months. Super glad I bought it. My cat loves it too

Exceeded expectations in every way.
Size: 2' x 3' (Sheepskin shape), Color: Gray Tip, Size: 2' x 3' (Sheepskin shape), Color: Gray Tip
I purchased a pair of these a week apart, because the price seemed too good to be true. Instead, they have exceeded my expectations. I own a Buick with leather seats that look incredible, but are not comfortable on long trips, and my wife and I were preparing to leave on a 2200 mile round trip vacation. On the first day, we drove 700 miles, much of it through desert. We were tired when we reached our destination, but comfortable and cool for every mile of it. The sheepskins have made such a difference, that I have never removed them from the car. It is now July, with triple digit temperatures every day, surrounded by desert. The sheepskin keep us cool on every drive. I could have purchased sheepskin seat covers, but these provide the same comfort for a fraction of the cost. Yes, it takes a small amount of effort to adjust them when you first get into the car, but I don't even think about it any more. As far as the quality, there is no shedding, no smell, and no discoloration. We have put over 4,000 miles on the car since I put these in, and I have no complaints to register.

Great product: thick and cozy
Size: Single Pelt/2 ft x 3 ft, Color: Natural (Ivory Whiite)
This is a lovely, thick sheepskin. I’m using it to drape over a chair. It’s very soft. The color is a natural white. Arrived quickly. The price was great for such a wonderful sheepskin.

Love it!
Size: 2' x 6' (Double Pelt), Color: Linen, Size: 2' x 6' (Double Pelt), Color: Linen
Exceeded all expectations. Bigger than I imagined it would be, super soft and thick, beautiful color (Linen), and no funky smell at all. It seems very durable. After running my hands all over it, no shedding occurred. I have yet to sit on it myself, though, as my cat claimed it right away - didn't even wait for me to remove the tag! He's been there for hours and I'm thinking I've lost my snuggle buddy, so I bought two more in the smaller size so he can have his own on the bed with me at night. I am so amazed by the quality, feel, and color. I can't believe I almost let other reviews deter me from this purchase. 100% thrilled with this beautiful pelt. Absolutely recommend! UPDATE: I received the other 2 purchased. Just as soft, just as thick, consistent color (Linen), no shedding, no smell. They have been in use for several days now without any issues. Love them all - and my snuggle buddy is back! 🥰

It’s wonderful!!
Size: 2' x 3' (Single Pelt), Color: Brown, Size: 2' x 3' (Single Pelt), Color: Brown
The product is wonderful! You know it is real, coz the smell doesn’t go away. I use it to meditate and cannot how nicely it created the perfect comforting barrier to help elevate my experience. I however want to find alternatives coz I stopped using animal products after turning a vegetarian. The size (it is bigger in person than in the pic) and color(brown) are perfect for what I do and doesn’t need much/any maintenance! The white however needs a lot of attention and care.I’m sure it would last a decade and the weight is just right too!
