Problems with SCT Tuner after Alternator Replacement
Just got my 2006 GT back from the Ford Service Center after replacing the alternator but it's not running smoothly and when I ran a check using my SCT tuner the codes indicate that it is running lean so I tried to reinstall my bama custom tune standard setting it comes up incorrect vehicle code 1017 so I can't re-tune. Does anyone have any experience with this problem ?

If they did flash your car back to stock, your SCT device is now useless. You'll have to send it back to SCT directly for the device to be unlocked. I would give them a call and see what they can do for you.
Let me know if I can be of any assistance or if you need some help from me.

This is a very common practice. Dealerships will always check your PCM for updates. If there is an update, they'll do it and most likely won't even tell you. That's why it's never a good idea to hide the fact that your Mustang is tuned. I told my dealership that it was tuned and I even return the car to stock before going in for service to insure that they don't mess anything up.

I have never experienced a Ford dealer re-flashing my tune, but I know it is a common practice at dealerships and have heard of it happening before. Besides making sure I tell the service manager that it has a custom tune and for the tech to be sure NOT to try re-flashing it, I double down by putting a piece of black electrical tape over the OBD port, with a tag attached stating that the car has a custom tune installed and NOT to re-flash the computer......better safe than sorry and a having a hassle to go through, as well as possible injury to the engine.

If you have a custom tune on your car, the SCT device stores the stock tune and registers that the car has a custom tune loaded. If the dealership re-flashes your PCM back to stock, the SCT device and your PCM are out of sync at that point. That's why it's a good idea to return the PCM back to stock before taking your car in for service so that doesn't happen.

Just be happy SCT made a change with the X3. With the old X2 when the dealer flashed the computer with a new stock tune and you then tried to load your tune back in, it turned the computer into a brick. You had to get it towed to the dealer and they had to load a complete new stock tune into it. Then you had to get tunes for the X2 based on the new computer code. Don't ask me how I know this.

I hope you returned to stock before it went in , then checked to see that your code matched before uploading any tune. I alays tell dealer to never re flash or else , actually I don't trust my dealer any more Suburban motors in Victoria BC can't even install a passenger window without botching it up ,nor can they fix an aluminium hood paint issue 😠

Flashing back to stock to take to dealer, not an option for me.
If they do an update, and you did flash back to stock, there still is a chance it may not take your tune even still. Could come up with a different calibration code and the tuner wont like that.
Speaking of dealers, need to take it in for that air bag inflator recall.

This is the best thing to do.

This is exactly why SCT and every tuning vendor requires always re-flashing back to stock before taking your vehicle back to the dealer for servicing..
Even if the dealership updates your stock calibration code ? Your programmer will accept the new PCM code, provided your PCM has been returned to the original OEM calibration/code first..
