Either way, you have to remove the ECU and send it to Whipple, Doug can't do anything without Whipples Stock Programming they put on to the ECU! I pulled my ECU and sent it out and got it back 2 days later, only b/c I paid xtra for the next day shipping..You can't send the ECU out until you have the supercharger in hand anyways...Don't start the truck on Fords Stock program or otherwise you will kill something really good if the supercharger is on the truck...Get the insurance on the package you send to Whipple, so if something supposedly happens, you can get another one....
