I have a guy who has a SCT Tuner and a JLT Intake he will sell for $250. How can I tell if the tuner is unlocked? The only issue I have is that and the JLT Tube is painted Legend Lime my car is Black

 

Should be able to plug and play, only if he infact has unloaded the programmer.

 

It is returned to stock if the original car was tuned back to stock. You can verify this by plugging the tuner into a car and going to the device status or device info screen.

And a can of spray paint will cure that Legend Lime disease.

 

leave the legend lime paint on there it worth at least 4 more hp

 

That's a good deal if the tuner's unlocked. You'r planning on ordering tunes specific for your code right?

 

Yes, but how do I know the tuner is unlocked?

 

You won't know til you try.
