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

WIDE Dress Shoes With SUPPORT
Size: 10.5, Color: Brown
I've seen dress shoes and worn dress shoes before, but these are simply the best dress shoes I've ever worn my entire life. 99% of dress shoes have the same problem, they have the thinnest little soles that offer no support. BRUNO MARC HAS SOLVED THE PROBLEM. These dress shoes not only support wide feet like mine who historically have had and still have little support in the market, but Bruno Marc has wide options that fit perfectly, and the support with the thick foam sole is so needed and awesome. I had a pleasant surprise putting these things on and there being some tactile grip enhancers inside the shoe so you can feel the shoes better and get a little tickle / massage while you're at it. These things are dripping with style, easy to wear, and while they might look firm on the outside, on the inside the shoe just has such a nice flexibility and foamy feel, the top where the top of your feet feel the roof of the shoe, it has such perfect ooey gooey support I can't believe it. The outside sole also has this neat tactile feel. The durability looks good and feels good for now.

Select your true size.
Size: 12, Color: Brown
True to size. I wear a 10.5 W in dress shoes, tried them on and they felt a little big. Returned for a 10, bad mistake. When I wore them they hurt my feet around the toes area due to the narrow toe part of the shoe. Suggest a true to size pick when buying. Other than my error the shoes felt great.

Snazzy Looking and Cost-Effective Dress Shoes
Size: 9.5, Color: Black
The shoes fit great and look very nice. They keep their shine and comfortable. I would say there are two drawbacks. 1. When you put them on, the tongue pushes up far and you have to pull it back. 2. There is little to no arch support and would recommend insoles if you have any foot condition. I haven’t had these through a snowy and salty winter.
