So....I just recently bought an XCal2 for my '03 6.0l. I'm just learning all the tuning/flash lingo, so now i'm trying my best to keep up with all this. I've already tried all 3 programs from my SCT, without returning the vehicle to stock even once. I'm assuming (1) I haven't screwed myself yet, because I haven't updated the device or have I?? and (2) Either way, I need to call SCT and get the dump file so I can save my stock tune to my computer. The last question is, when do I need to unlock my programmer from live load?? Thanks a lot fellas and ladies...
The tunes are awesome compared to the Superchips Cortex I had a few weeks ago.
