Why Choose Piston Twistin?

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

  • Bigger turbos

  • Larger injectors

  • Modified or stroker CP3s

  • Additional power levels

  • Hourly tuning support

Those costs add up fast.

We don’t do that.

✅ Our Pricing Philosophy

  • One flat price

  • Any turbo

  • Any injector size

  • Any CP3

  • All DSP5 power levels included

  • Unlimited revisions

  • No hourly support fees

Your truck evolves. Your tuning support evolves with it.


🔧 Custom DSP5 Switch-On-The-Fly Tuning

This package includes five independently calibrated EFI Live tunes, selectable on-the-fly using the included DSP5 switch.

Each power level is:

  • Built 100% in-house

  • Tuned specifically for your modification list

  • Designed for a specific use case

  • Refined using datalog feedback when needed

This is not stacked or generic tuning — each DSP5 position is its own calibration.


🎛️ Typical DSP5 Power Level Layout

(Final layout customized to your goals)

DSP5 Position Use Case Description
Position 1 Optimized Stock Clean daily driving, best MPG
Position 2 Tow Heavy towing with safe EGT control
Position 3 Light Tow / Street Balanced power and drivability
Position 4 Street Performance Aggressive daily driving
Position 5 Max Effort Built trucks / fun use

Power output varies based on turbo size, injectors, CP3, and supporting modifications.

Office Divider
Size: 5 Panels, Color: Grey
This office divider is well made and easy to assemble. All you have to do is install the feet. The panels are only about an inch thick, but they work surprisingly well at muffling unwanted background noise.

Easily Create a Workspace
Size: 5 Panels, Color: Grey
Such a great design. I am loving the versatility of these - very easy to set up and also to store. THe color is perfect for them to blend into the decor. While they don't cancel out the noise altogether, they reduce it and decrease distractions. No installation needed - has its own supports. Built really well with good materials - sleek and sturdy and solid. They have increased the privacy and have helped make a great space without difficult construction. Work well and they are great value for money - instant privacy and space.

Perfect for my company's temporary needs
Color: Gray, Size: 72" wide, 66" Tall
My company ordered multiples of these dividers to separate desks in much smaller temporary space we had to use after our offices were flooded in August 2023. (Yeah, I know - just getting around to reviewing them now!) These fit the bill perfectly. Granted a bit of privacy so we weren't staring at the employee next to us. Easy to put together; excellent value.

Okay for privacy, not a sound wall
Color: Gray, Size: 72" wide, 66" Tall
Ordered this for a home office, it is easy to put the panels together, one man job. They look nice, stand up well, and gave privacy and seperation. You can tack a white board to them. These panels have absolutely no sound reducing properties that I can ascertain, so if you are ordering them as 'accoustic" type panels you will probably be disappointed. For making a cubicle they perform well.
