98 C5 Base Spark Plug Gap
Hey I am going to get my 98 C5 dyno tuned soon. Has no cats and headers; motor is otherwise stock. I bought NGK TR55 spark plugs and was wondering what the recommended gap would be for my mods. I seen some people say anywhere between .44 and .55, but wanted to see what opinions anyone else had.
