Improvements from VMP custom tunes (varies by application):
- Removed speed limiter (do not exceed tire or driveshaft rating)
- Safely raised rev limiter 200-400RPM.
- Advaced timing for improved response and power at all RPM ranges
- Optimized air fuel ratio for more power at WOT
- Permanently turn traction control off (specify when ordering)
- Optimized engine fan cooling on/off temperatures for less heat-soak
Our tunes greatly improve driveability and power at all throttle positions. We tune for all around driveability, not just WOT performance. We feel that a good tune offers low-end "Torque" and "Race" type WOT performance all in one.
Examples of the up to 3 tunes you can order:
Q: How do I install my tune on my Tuning Device
A: To load custom tune files on SCT click here.
Q: How do I find my computer code/strategy/part number code?
A: On 2004 and older vehicles the code can be found on a small white sticker on the passenger side door jamb or door. If this sticker is worn off you will need to look on the computer itself. On Mustangs the computer can be found behind the passenger side kick panel. On trucks the computer can be found going through the firewall on the passenger side, often the code is visible from underneath the dash. On large cars the computer can be found under the drivers side dash.
