return to stock b4 custom tune?

[goosegodz]

I finally got around to getting some custom tunes and was wondering if I had to return to stock(im running a canned tune from SCT) before I load the custom tune?

Thanks,
Todd

I don't believe so. I have switched between different tunes and never returned my truck back to stock before doing so, and I've never had any trouble..

Just be sure to save your stock tune to your PC before hand, just incase something does go wrong.

I always return to stock when switching tunes. Just did it tonight actually. It's mostly a just in case thing. It only takes 10 more minutes to peace of mind

Not to hijack the thread, but, I found the free Sparatan tunes for my strategy and tried to load two different tunes on my truck. Neither time the truck would start. I returned it back to stock hoping I didn't damage anything; still nothing. I reloaded with my custom tune and she started right up. So at this point I think my stock file is trashed some how. Remember you get what you pay for...

Thanks guys, I saved my stock file to pc right after I flashed the canned tune. When I did I got a "VIN not correct alpha numeric error". 3 files did transer. flash.lbu, stock.lbu and invalidvin.sul. Anyone have any info on that?

when did this became possible? I wanted to do this years ago but I believe I was told by a tuner that this wasn't an option. Can i do this using liveload? Thanks

Yes, on Liveload. You will see a option for "Get stock file". This will send a copy of your stock file to your PC. Then if you have issues where the SCT device loses/corrupts the stock file, SCT tech support can send you a recovery file that will allow you to load the stock file form your PC to the SCT device.

Forgot to mention, check out the "sticky area", Vivian has a explanation of why.

Glad this is an option finally. Thanks Pooh.
