I've been working with Lund on a tune for the race gas I'm running in my 2016 Mustang GT. The gas in question is Sunoco 260 GT Plus 104 unleaded race gas. I had been asked to re-gap my plugs as part of the tuning. When I removed the plugs from the block I saw orange all over them. Let's find out why.
