Question:
are engine programmers good for your engine?
Option 1: yes
Option 2: no
Option 3: buy a supercharger and listen to the whine!
Option 4: slap on a nitrous kit and hope the pistons stay in the block!
So my buddy just bought a 2012 GMC Sierra with the 6.2L he has been wanting to uprgrade the performance of it so I suggested 1 option would be the programmer. Apparently he has a couple of other buddies that really don't have any good marks for programmers. They say it will blow an engine. I have never heard of this. Granted I really haven't looked into the pros and cons of them, but I have a couple of friends that had them and have never blown an engine. Just curious what everyone thinks. Thanks
