I recently bought tunes from TP and was waiting for th 87 octane to get down far enough to put 91 so I could try that tune. Anyway I gassed up and downloaded the 91 octane tune and as I was doing it I remembered that on the superchips tuner you had to take out whatever tune was in there and then load what tune you wanted. The X3 just started downloading the 91 tune into the truck. Is this normal. Should I be worried about it.

 

Nope, you can just switch tunes. No need to return to stock.

 

Don't worry. Your stock tune is stored in your hand held device. You can return to stock by following the on-screen prompts.

 

It wasn't so much the stock tune I was worried about. I had the 87 in there and then filled up and changed to 91. I was just worried I lost my 87 tune.

 

Your custom tunes are stored in your tuner. You didn't lose anything.

 

Nope, you're good man. Check your inbox, I answered the question.

 

got it

Thanks.
