Some great info so far. I wish I could "safely" slow down. Here in Miami, the average highway speed is about 75. Everyone speeds. When I first got the car I thought I was going to die because it was such a huge difference from the v8 ex-daily. I used to go about 80-85 in that for its best economy. I will try to slow done this week and see what happens. I'll have to leave at about 5:30 if I do 50. So I think I'll beat most of the traffic at that time. Now is it safe to pull the knock sensor after letting the engine run hotter and take in warmer air thus running leaner? I know that the PCM will use the knock sensor to pull timing if the sensors senses detonation.

Thanks for the info, Keep it coming!
