Question Spark Plugs Question
I recently got my car dynotuned after changing my cam, and to my surprise afterwards, I forgot to change my plugs(ACDelcos). They have been on my car for the past 30,000 miles and looked kinda black and white when I took them out of my car yesterday when I replaced them with tr55s. What I was wondering is, did the old plugs have any affect on my dynotune, and will I run too lean at wot now with the new plugs, since the tune was for old plugs?

thank you

Should be fine, you might want to pull a few plugs from each side in 100 miles or so just to see how she's burning.
