At checkout please provide vehicle VIN so a proper file can be build, in some cases a 'stock read' is required.
Please send vin and AutoCal serial number, if using a Flashscan, just the vin is all we need.
We may need a Stock read of your ECM.
Please allow about 3 hours for us to build the file. We do work some weekends but this is not guaranteed.
