Great start!

Thanks.

On the 22.7 mpg return trip from the hills, I was running smarty revo #0 w/ tq1 tm4 rp2 sl55... Was looking for advanced timing (with the tm4) and better atomization (with the rp2) and less power overall and a brick wall limiter on speed to avoid temptation. It worked, netting me more than 2.5 mpg additional over my last run.

As for aero, a better air dam has been on my to-do list for some time, but I don't think I'll be messing with it until I get a replacement bumper. My bumper does need replacement, and I'll be going aftermarket with a baja/prerunner style so I have the least amount of additional aero drag (but some, because I do want something to protect the grill). So that way I'll only be building one air dam instead of building twice. But, the more I think about it, building again when I get to the point of buying that new bumper I'll have already had some trial and error and experience building one.

Last night, I spent most of the evening obsessing and sketching designs for an automatic louvered grill which would open just enough at any ambient temp to let the truck maintain 190-200 degrees, blocking off the rest (and blocking entirely for faster warm-ups.)

Don't know if I can pull it off, but the more I look at it, the easier it looks to be done on a stock-style grill vs. the "big open mouth" style that's on the truck now.
