So Puerto Rican 335d, you live in a similar climate to me (Florida/Georgia), hot and humid. I've noticed as the outside temperature has started into the 90+*F my car is experiencing some heat soak issues. When its cold I have full power but after some stop and go low speed city driving in the heat there's a drop in power.
Since you're running the Wagner IC, what's your experience in the heat driving your car? I don't expect more power from an IC, I want usable power for longer (less heat soak).
I am used to heat soak with my Shelby GT500, they're notorious for it with the stock heat exchanger (air to water IC). So a common mod on these cars is a larger heat exchanger with fans and it makes a huge difference.
