You will need the dealer or Star/Xentry to reset the error or determine what the issue is.

Go over your install and see if maybe you disturbed an electrical connection for the SRS. If the battery was not unhooked a SRS code can be set even if the system is operating properly.

+1. It's completely unrelated to the supercharger installation and very likely a result of a temporary disconnection of some SRS connector during the s/c installation if the battery was left connected.

It is related by them doing what you said most likely. I didn't have the warnings before so it's related some how.
Thanks for replies

Once you scan the system and get the fault code then you will know where to look.
There are inertia sensors under the hood or bumper that may have been disturbed.

It may just be a matter of clearing the fault code with a scanner. Often times even though the fault is no longer present the warning light will stay on until the fault is erased.

You don't need Star/Xentry to reset SRS. Any scanner than can read the individual modules should be able to do it.
