Actually Turna, I just realized the last time the headers and 2.5" dual exhaust were on this 260, it had a dying TH350. So I barely put any highway miles on it. It is probably now super lean thanks to the headers and probably the shitty cooling this car has always had. I plan to switch back to a thermal switch to turn on the fans. Is there a durable switch for the intake with a lower set point than 195?
