why would you need a tune for an x-pipe? doesn't seem to make sense at all, unless it's an ORX

When changing custom tunes, I never return back to stock and haven't experienced any issues. =-)

I don't return to stock either. The tuner holds 10 tunes. They want you to return to stock just in case something goes wrong with your tuner when you plug it in to the computer to load tunes. It could update and reset, dropping your stock tune forever if you didnt save it first to the computer. I know...it happened to me.

I havnt had the stock tune in my car since I purchased the SCT device a week after I bought my car 3.5 years ago. Flash in the good stuff, screw the stock tune.

No need to switch back to stock when changing tunes. However, you should return to stock when updating the firmware on your tuner. Otherwise, you might lose your stock tune if the firmware update fails.

Correct - only return to stock when trying to update the tuner's firmware (which has never worked for me). I've read of it taking 5 hours or more? I always get tired of waiting after 45 minutes of no activity....

Only took 10-15 minutes for me.

I heard that too but my car wont run on the stock tune anymore. Updating my firmware was frustrating as hell. Took me a couple of days and a friends help to finally do the sequence to where it would finally update. POS system IMO.
