If i were to get the diablo tuner, would i be able to return it to its original tune without the dealership noticing, cause i would hate to void my warranty

 

Take a look here

 

Most likely dropping a new tune in is not going to void your warranty. But if you think your dealer is a stickler, the Diablo saves your stock tune on it and you can upload it back to your car before you go in for service. Your dealer is none the wiser.

 

1. Aftermarket parts don't void your warranty. If someone hassles you, mention the Moss-Manguson Act to them and see what they say. (I recommend you google Moss-Manguson)

2. The tuners first read the stock program and store it so you can go back to it if you want.

3. If you have an automatic transmission, I highly recommend the SCT2 tuner as it will let you change the transmission shift points AND change the line pressure for a good firm shift!

Hope this helps.
