Okay, so I just downloaded my current exhaust timing map, and it seems that the first cam is for normal coolant range, and the second cam is for low coolant range. There's quite a big difference between my current maps and what is listed as stock.

Now the question is where to start. Most of my driving is in the 2,500 to 3,500 rpm range at 40-70% load, and I'm really looking to focus primarily on my highway mileage (3,000-3,500 rpm and ~60% load).
