How our F250 & F350 7.3L Custom Tuning Works Stage 3's 5-Star Custom Tuning Step-by-Step:
1. You place your order for 5-Star's Custom Tunes.
2. Stage 3 sends you a "blank"
tuner without custom tunes.
3. You hook the tuner into your truck and pull its ECU strategy code.
4. You fill out our online tune form
with the information from your truck and its strategy code.
5. If your truck has Ford's latest strategy updates, we'll forward your information over to 5-Star and get your tunes created.
6. Once 5-Star creates your tunes, you will be emailed a link to download them from our Google Drive.
7. Download 5-Star's tunes to your PC and then load them to your tuning device using SCT's Device Updater Software.
8. Now you can successfully load your 5-Star Custom Tune of choice into your Super Duty.
After you order this system, you are sent a "blank" tuner without any custom tunes. Please be aware that SCT's devices and software are only compatible with Microsoft Windows computers, and will not work with Mac OS X, Linux, or other operating systems. Once the tunes are successfully loaded onto the tuner, you can then start to load your tunes into your truck. If we find that your truck is behind on its latest TSB strategy updates, we may require you to have your TSB updates performed at your dealership of choice. Read our TSB Update blog post. Off-Road Exhaust Systems:
5-Star can no longer provide custom tuning for off-road exhaust systems that delete catalytic converters. 5-Star can only tune for catted exhaust systems. However, 5-Star WILL NOT disable your rear oxygen sensors, which may result in a check engine light.
