⚡ Why Single-File Tuning on LML?

Unlike earlier Duramax platforms, LML trucks do not support true DSP5 switch-on-the-fly tuning.

Because of this, the cleanest and safest setup for an LML is:

  • One properly calibrated tune

  • Matched exactly to your hardware

  • Optimized for your primary use

This avoids unnecessary complexity and ensures consistent drivability, reliability, and performance.


⚙️ Typical Power Options (Final Tune Is Custom)

Power output varies based on turbo, fuel system, transmission, and supporting mods.

Tune Style Estimated RWHP Gain Ideal Use
Optimized Stock +20 HP Clean daily driving
Tow +40–60 HP Heavy towing
Street +80–100 HP Strong daily performance
Performance +120–200 HP Built trucks / race use

Your tune is custom-built, not selected from a preset list.


🧠 Why Piston Twistin?

Many tuning companies:

  • Charge extra for turbos

  • Charge extra for injectors

  • Charge extra for CP3 upgrades

  • Bill hourly for revisions

We don’t.

  • One flat price

  • Any turbo

  • Any injector size

  • Any CP3

  • Off-road delete included

Neat gadget
Color: Gold
Neat little gadget. Works great, easy to use and has a light indicator for temperature range. Keeps a cup of liquid hot right to the bottom.

My tea stays warm to the bottom of the cup!!!
I am so glad I purchased this mug water. I drink tea all day but it cools down quickly. Since I purchased this mug warmer my tea stays hot to the bottom of the cup. The temperature is adjustable so you can keep your drink at your desired temperature. The top is glass and wipes clean easily. I like the rubber gasket that fits on top of the warmer. It keeps your mug in the center of the warmer and should you have a spill it catches the liquid. I've been using it every day for over a month now and it's going strong and is reliable. Perfect for personal use or as a gift.

Keeps my coffee as hot as I want it to be
Color: Silver
This coffee warmer is much better than the candle warmer that I was using for my coffee before. With a range of 3 temperatures, I have a choice of temperatures from hot to very, very hot, and the warmer shuts itself off after a while, just in case I forget. The description advises that ceramic cups do not retain heat as well as flat-bottomed cups, but I have not found that to be a problem. Coffee in my ceramic mug stays as hot as I want it to be. The knob on the side makes this warmer easy to turn on and to select a temperature, plus I feel that it is a good value.

Perfect Mug Warmer
Color: Black
I bought this to replace one I'd had for more than 25 years & I'm glad I got this one. Keeps my hot drinks hot for hours & will shut off after that. Quickly heats back up when needed. Very sleek looking. Easy to set up. Just take it out of the box & plug it in.

I love it for my workspace! Hot tea all day
Color: Wood Grain
I love this item. The size is perfect, as I prefer something less bulky for my work desktop. It isn't as fancy as others that has the digital display screen, which is fine by me, because I don't necessarily need that. The knob and different colors that indicate the temperature range works fine. The temperature on this thing works fantastically well for me. Using it on the lowest setting keeps my drink nice and hot in a cold office. I use a heatproof glass teapot with this and its a good fit. It keeps my tea hot throughout the day, so I am able to pour smaller amounts of drink and take my time sipping it throughout the day without worrying that it will get cold. At point I almost forgot that it has an automatic shut-off safety feature when I noticed it was off. So that is a good feature to have. I highly recommend this.
