I have on order an 87 Performance Tune for my Gryphon CS. It was ordered about a month ago, but I havent got the email with my custom tune yet. I will be going from 2 - 4"X9"X14" mufflers to 2 - 4"X9"X18". Does anyone know if I am going to need another tune or is the muffler change not going to affect my original tune on order?

 

No revisions will be necessary for muffler size changes.

 

thanks 88!

 

If you haven't done so already, please install Fusion (it was on the disk that came with your CS) and establish a Fusion account. Then, after you set your truck's tune back to stock. start Fusion, connect your CS when instructed to do so and let it check for firmware updates from Edge, which it will install if there are any found. Then you can return the CS to your truck.

Your CS's firmware needs to be up to date BEFORE Bill puts your custom tunes on the Edge server, or the firmware update will probably wipe out your custom tune right after it is installed.

Thanks Jack. Already got it covered, but I appreciate the reminder.
