Like the title says, I was trying to get the SCT performance x4 hand held scanner to hook up to my computer last night and was having a tough time but finally managed it. Under the "device settings" I hit check updates and it downloaded 235 updates. I just read I should have brought it to the factory tune before doing this then re install the custom tune after? Is this true?
Im new to this program and just trying to figure it out?
Any help is appreciated,
