which rear end do you have. The 411 or 373? I'm assuming the 373 since your milage is up around 18. That looks good if it is hand calculated, the lie-o-meter on the overhead can be grossly off. Mine said 27 last week. I wish....
Normally I see 15 around town and 18 on the highway if I can control my heavy foot. Towing is a different story - 11-13mpg with a 10K fifth wheel camper.

When you are driving 70 mph in OD and if your rpm's are at 2,000 then you have the 3.73. Looks like the tag numbers might show that also but I don't have a secret decoder ring to figure it out.

I'll let this one go for now. I did just do 21.2 on Jody's 60T setting city driving but right now I'm going to do 5 or 600 miles on his 80 setting, and it's so much fun I probably won't do so good. Man, you talk about blowing Superchips 80 HP out of the water, I was merging onto I-77 in NC this morning and I damn near scared myself with the WOT. The difference in the two chips is, Hell, I'm unable to describe it.
