Knock on wood, I've used 20% ALL THE WAY AROUND (except windshield of course) and have never gotten pulled over for tint. One time an Indiana State Trooper pulled me over for speeding (at night) and gave me a warning for the speeding and didn't say one word about my tinted windows.
Just had my smart done with all 5 pcs of glass at 20%. I've used this guy since the mid-90's.........he's GREAT!
And I agree with 'Docthrock'....did the CHIP actually HAVE a 'tint-meter'? If not, you might be able to get it thrown out. Do you have the receipt from your installation showing you're "legal"? Take that with you too.
Good Luck!
