Well, I'm back! I only drove from the dealer back home which is about 9 miles and 6 were highway miles. I took it pretty easy because I had my kids with me. It gets up to speed much easier now and didn't downshift in some spots I was used to with the 3.73s. I don't have much of a review with such a short drive but, I can say for sure, I noticed a difference and I am looking forward to doing some more testing!
Thanks for the reminder about the break-in. No one there mentioned a thing about that. I think they just wanted to get out of there for the holiday.
I need to change my signature now!

I posted the above gas mileage figures when I had the 3.73s. My first tank with the 4.30s got me 10.41 mpg. It's slightly lower than it was with the 3.73s but, it's been getting colder and I've been trending downward in mileage any way. I took it easy this tank to break in the gears. I'll let you know if it changes when I go back to normal driving!
