| The COBB AP tunes are extremely reliable and have been available for about a year now. They are huge tuners in the turbo game. I have never heard a bad thing about them. (Haven't looked that much to be 100% honest. I have the JB3 plug in play and I'm just waiting for a trip to my shop 1.5 hour drive both ways to have them remove it so I can sell it and upgrade to the Cobb)
I haven't heard about those codes, but I guess its just the risk you run when you mod.
