Heads Up Display

Any ideas on a heads up display problem? The numbers are randomly changing. Should I take the battery cable off to reset the computer since I recently upgraded to a high flow down pipe and a cat back exhaust?

Wrong thread or forum so your post has been moved to the regular part of the forum.

What part of the HUD display? The speedo readout, radio stations?

Also, please post the year and model.
