Tune Revision Policy
How revisions work after your tune is delivered.
What's included
Every tune order includes 3 revisions within 30 days of the first delivery of your completed tune (configurable values — final numbers confirmed at launch).
A revision is an adjustment to the calibration we built for the truck and combination you reported — drivability tweaks, shift feel, throttle response, addressing a data-logged issue.
What's not a revision
A new combination is a new tune: changed injectors, turbo, transmission build or tuning platform after delivery requires a new calibration, not a revision.
Revisions may require fresh data logs or an updated read file so we're adjusting against reality — we'll tell you what we need when you request one.
After the included revisions
Revisions beyond the included count, or outside the window, are billed at $150.00.
How to request one
Open your order in your SDPI account and request a revision, describing what you're seeing and attaching logs if you have them. Requests flow straight into the calibration queue.
