Check out Sunbusters up on 183 near Duval. I picked up a 2012 BP LE and had them strip the crap tint from the front windows and then do full ceramic tint all the way around. Max darkness allowed in TX on the fronts and the same tint over the factory tint in the back to just darken them up a little. If you want pics let me know (don't have any "before" shots).
I'm not affiliated with them in any way other than being a happy customer. When I was there, they had two brand new 2014 Corvettes, a BMW 6-Series Grand Coupe, a brand new M5, and a Bently of some kind. The guy said most of it was referred to them by the dealerships. They definitely know their stuff.
