That’s up to you. For basic configurations (adding a cold air intake, throttle body, etc) we can have a start up file to you within 1-2 business days. More involved tunes (blower upgrades, fueling upgrades, etc) can expect a base or start up file in 5-7 business days. At that point, the tuning process depends on how quickly you can get us datalogs and the scheduling of any dyno time, if necessary. We (you and us) should never take more than 30 days to complete a process for any reason. It’s generally more like a week, based on your availability.
