Return to stock or not for reflash?

[bsexton]

I have some work to be done on the truck and debating whether or not to return everything back to stock (dpf, cat, etc...) or to just detune the truck at the dealer let them do the work and reflash (I am about 4 updates behind) and then reprogram there. I have the lateset SCT tunes so the latest update is covered. The dealer is cool with the dpf and cat gone I just want to know if it is feasable to do what I am asking and if anyone else has and what the pros and cons are.

If you are running tuned, what do you need the reflash for?

Valid question. I guess I have read in a few places that you may see better results having your truck updated. Now if that is not the case and people arent really seeing any changes I won't however I guess another way to look at this is what do I need to do if by chance they flash me with it tuned. Like I said my dealership is good about mods so I dont want to waste my time returning everything to stock. If by chance they forget that I told them not to reflash and they do it is probably better to be de-tuned IMO. Again someone chime in. If it is no big deal to have a tune flashed over as long as you have the tune and tuner in hand to fix the issue at the dealership before leaving then I will just take my chances otherwise I would like to be prepared.

If the truck is flashed while tuned, you will have problems. It will delete your tune and lock the sct. If you set it back to stock then retune the truck when they are done you will have no problems.
