Revision 1 is guaranteed within 24–72 business hours after JRJ receives your stock read. This covers the first revision only; there is no guaranteed finish date or later-revision turnaround. Logs and follow-up requests are queued and handled in the order received. Progress depends on vehicle condition, parts, mechanical issues, equipment, usable logs and when you can upload them. Normal business hours are Monday–Friday, excluding holidays; weekends do not count. Eligible paid Faster Turnaround has separate Revision 1 terms.
How remote tuning worksBase Tune is a rough starting calibration for startup and initial driving, with two revisions; it may still have drivability issues and need further tuning. Choose Full Custom for Jason to review your datalogs and refine the tune, with up to five revisions for the purchased setup.
