Ever since I had my Procharger installed [6 months] there is this reappearing burn mark in the same spot [drivers bottom] of my FMIC. Its about the size of a half dollar, maybe alittle larger, and its almost a perfect circle - the middle being the darkest and then fading outward. It looks like someone just takes a cigarette lighter and holds it there for a few seconds. It always wipes right off with every wash and never gets any bigger, smaller, or 'denser'. The 1st time it happened I thought maybe a cigarette hit it and stuck and continued to burn on it... but it keeps comming back...

Any ideas?
