Why Piston Twistin EFI Live Tuning Is Different
At Piston Twistin, we don’t punish customers for modifying their trucks.
Many tuning companies advertise a low base price, then charge extra for:
-
Aftermarket turbos
-
Larger injectors
-
High-flow or stroker CP3 injection pumps
-
Tune support billed hourly
Those costs add up fast.
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 tuning support shouldn’t stop when the clock runs out.
