any reason to have extra pcm?

[Tahoe03mm]

question, is there any reason to have an extra pcm? I'm getting the bb 93 tune and I'm wondering if I should keep the stock one for any reason or send it back

sorry for posting in wrong thread :(

I kept mine. If you ever need to send it back in for a retune its good to have a spare.

yep, helps with downtime when u need to swap PCMs. But, if u can deal with a week downtime, then no need for one.

Unless ur vehicle is under warranty, then I would keep the stock one for swapping when bringing it to the dealership.

That too, although I have heard that they wont pick up that it is tuned unless they are looking hard for it

im sure, but then again, dealerships are always looking for ways to screw you out of warranty work, lol.
