Hello,I have a 2003 vibe GT and have been putting only supreme gas in it since the owners manual says to. With gas prices where they are I am wondering if I could switch to regular. If I do how much (if any) damage will i be doing to the GT engine.Thanks for any advice,Rob Sullivan

So has it been confirmed for sure that this MOD will work with a Single CD unit?I have a 2003 GT single CD unit and have been itching to get my ipod plugged in. I'm tired of the itrip.If it is possible, I might try to throw a document together of instructions as I MOD mine based on all the good info...
