This is a delete tune file — sent digitally after purchase. It is written for trucks running without a DPF, DEF system, or EGR. Built for off-road use only.
What This Tune Adjusts
| Area | What Changes |
|---|---|
| Throttle Response | The lag you feel when first pressing the pedal gets removed. Input is immediate from tip-in. |
| Torque Delivery | Power comes in earlier through the RPM range — you'll feel it when towing, hauling, or holding highway speed. |
| Fuel Economy | Injection timing and VGT operation are recalibrated for better efficiency. Most drivers pick up real MPG gains. |
| Exhaust Brake | Pushed to maximum output. Your saved driver memory settings are not affected. |
| Auto Start/Stop | Permanently disabled. |
| Safety Strategies | OEM engine protection tables are kept in place and recalibrated to match the tune. |
Tune Levels
| Level | HP | Good For |
|---|---|---|
| Stock Optimized | +0 | No extra power added. Focus is on cleaner throttle feel and better fuel efficiency over stock. |
| Tow | +20 | Builds mid-range torque for trucks that spend time under load — trailers, flatbeds, heavy hauls. |
| Street | +40 | A solid everyday bump. More response and pull for regular driving without going too aggressive. |
