I'm in Houston also and was experiencing some uncomfortably high temps while driving a couple weeks ago. I ended up removing and deep cleaning the radiator (30 years of dust/dirt/fur...etc), brushing/blowing out dirt from the other coils in the stack, installed a 170 degree thermostat and updated chip with lower fan turn-on temps from Marc Haibeck. I took it on a brief test drive this afternoon and it appears to be making a positive impact.

I'll try to go for a longer drive later today or tomorrow and report back. My bet is that 90% of the improvement came with the deep cleaning of the radiator.
