Dealer Detect SCT?

[05P0werStroke]

Can the dealer detect if I run a sct? Should I set the truck back to stock before I take it in for warranty work or is returning it to stock without a trace possible

Go Back To Stock Before Updating Your SCT

No matter what you will still have a foot print. The dealerships can tell if the truck has ever been programed.

What is the chance they will look for the footprint

Slim chance that they would look for or even care that it had been programmed.
The main reason you should return it to stock before it goes into the dealer for warranty work is because they might do a program/strategy upgrade without asking or telling you about it first.

I know cals hooks the computer up for everything besides oil changes

Anyone who's in 6.0s often enough can tell if it's programmed just by driving it. if it's in for a drivability concern then it's probably going to get driven.

if you return it to stock I personally have no idea how to tell if it was ever programmed

Always return it to stock before taking it in to the dealer, just for the sole reason that they might reflash the computer and then your chip will be wiped out. One of the first things a dealer will do with a driveability issue is to check the programming and update it if necessary.

As far as I know I've never heard of anyone being able to tell that a 6.0 or a 6.4 has had a programmer on it. I'm sure they will in the future though.

It epends on the work performed, If they do headgaskets they can see the spray/burn pattern on the pistons.
