Ah, I was going to ask why they were 50s, as my "tuner" tires were 205/40/17s. I see now what the taller tires are doing for you. Keep the engine revving lower in 5th, especially, and perhaps roll over bumps in the road more smoothly. I went with stock to have correct speedo, odometer, and mileage readings, since I don't have the Kiwi plugged in at all times.

I hadn't fully understood how to integrate DFCO in my driving technique, but I certainly could benefit from it after reading about it in more detail here and especially your posts on the DFCO working above 1500rpm on the xB. I could absolutely have benefited from that on the hills around Tahoe and driving down from Tahoe where I needed to turn on my engine after EOC to have enough power in the brakes. I had previously been using the parking brake occasionally as a "drag brake" and windows down (the Box catches wind nicely with the windows down, lol) but in faster sections or when coming on traffic I had to bumpstart to get braking power back. Now I can DFCO alternating with EOC (EOC when I need to pick up speed by using gravity) down those mountain passes - good call!

I'm in Oaktown, didn't realize you were so close. Busy schedule of 46+ hours per week (especially around the holidays) and lots of responsibilities at home, along with trying to get enough exercise every day, but we'll have to find some way to get together.
