LMM Duramax EFI Live Custom Single Tune — File Only (2007.5–2010)
In-House Off-Road Calibration by Piston Twistin
This product is for customers who want a single custom EFI Live tune file for their 2007.5–2010 LMM Duramax, delivered as a file only.
You’ll receive one professionally calibrated tune, built 100% in-house by Piston Twistin, designed around your exact truck setup, driving goals, and supporting modifications. This tune is intended for off-road / competition use and includes full delete calibration where applicable.
This is not a canned tune or mass-produced file — every calibration is built specifically for your truck.
🚨 OFF-ROAD USE ONLY — IMPORTANT NOTICE
This tuning includes off-road / competition-use calibration and is intended for vehicles not operated on public roadways.
✔️ EGR delete support ✔️ DPF delete support ✔️ Off-road exhaust configurations supported ✔️ Proper diagnostic logic handling
By purchasing this product, you acknowledge that your vehicle is used in an off-road, competition, or closed-course environment, and that compliance with all applicable laws is the responsibility of the vehicle owner.
🔒 IMPORTANT — PLEASE READ BEFORE PURCHASING
✅ Single EFI Live tune file
✅ Custom-built for your exact setup
✅ Requires an EFI Live AutoCal or FlashScan (any generation)
❌ EFI Live device not included
❌ No DSP5 / Switch-On-The-Fly functionality

What Is a Single File Tune?
A single file tune is one fixed calibration that delivers consistent power, drivability, and reliability every time you drive.
No switching
No added complexity
Ideal for daily-driven trucks, work trucks, and customers who want a set-it-and-forget-it tune
This option is perfect if you don’t need multiple power levels and just want your truck dialed in correctly.
