FYI,
Alot of people are asking why our dealers are tight asses or why we return to stock tunes. There's a perfectly good explanation and it's really not because the dealers are tight azzes:
If the dealer reflashes ECU or PCM, your strategy code no longer matches. This is the first problem. Your SCT now needs to go back to SCT to be rematched with new PCM code before you can use again.
For those of us that insert a valet tune (so the dealers personnel cannot beat on your supercharged car while servicing soething simple like a recall), we now cannot put the performance tune back in because the SCT comes up as unknown. You are now stuck with a car that is driveability limited until you can send out and receive back, your SCT.
Many dealers could care less about the performance parts. Those of us with dealers like that are very fortunate. I'm one of those people myself. However, I don't trust any techs, and therefore I insert my valet tune if I ever have to go to the dealer. For these instances, I inform the service manager to not reflash, and as Dark mentioned, I place a Sticky note on the dash as well as over the diagnostic port, just so I don't get held up for 7 to 10 business days waiting for my SCT to be rematched..
In my case it's not an issue of removing parts at all, for others it is.
