take it to court, if you have pictures of your car stock, give the judge that to show that you "removed" the tint. The court hate trivia things like that and jurisdiction are depended on evidence and since you have the evidence and the cop for then doesnt since all you have to do is "remove" the tint, then you're safe. Judge will drop and will save you 90 bucks.
and your question, i have to say they have the same tint measure but!!!!! its retarded, it measures more than it was suppose to, its quite inaccurate. i hate ffx, oh the cops of ffx.
