I think my battery is toast. If I take the battery out of the car and put a new one in will the computer remember the stock tune or will it still have the custom tune? And if it will go back to the stock tune, will I have a problem re-installing the custom tune if I didn't put the tune back to stock before changing the battery? I have a Diablosport Predator. Thanks.

Your custom tune will still be there after you replace the battery, but the engine's idle may be a little squirrely. Refer to the procedure in the battery maintenance section of the owner's manual to help the PCM re-learn the idle strategy.
