Why Piston Twistin DSP5 Tuning Is Different

Many tuning companies:

• Stack power levels on top of one another

• Bill hourly for revisions or support

We don’t.

✅ Our DSP5 Pricing Philosophy

• One flat price

• Any turbo

• Any injector size

• Any CP3

• Off-road delete tuning included

• Unlimited revisions

• No hourly support fees — ever

Your truck evolves. Your tuning support evolves with it.

• Five independently calibrated power levels

• Off-road EGR & DPF delete tuning

• Stock factory calibration included

Each DSP5 position is tuned separately — not scaled or copy-pasted.
