error 150

And, bigredrig, just as an FYI to you and everyone else: Having to disconnect the battery is NOT a reason to set your truck back to stock. You did not need to do that at all.

There are really only 4 situations when you should return your truck's tune to stock:

1. Take the truck to the dealer for service. They sometimes "flash" the PCM to correct problems with the "stock" tune and the stock tune needs to be there to avoid problems.
2. Need to update the firmware or other information on the programmer via a PC. Return your truck to stock before you do this.
3. Return the programmer to the manufacturer or tuner to correct device problems.
4. Sell the programmer to someone else or want to use it on another vehicle. As long as there's a "tune" programmed into YOUR truck, the programmer is married to your truck and will not work on any other vehicle! (Note: if your programmer has custom tunes, they will not work on another vehicle.)

Just leave the current tune alone in all other cases.
