So I'm contemplating on either getting a racechip or vividracing chip. I've read all the stories about spark plugs and what not. My question is I know theres different settings but I'm not planning on running race gas or anything higher than 91, will that be ok? without replacing plugs? Just have it set on anything besides 91+ race mode. I'm even planning on getting the basic GTS model and not the black. Any advice or suggestions would be appreciated.
