Yeah, gas mileage isn't my #1 concern, I just didn't want to to drop off significantly...thats all. That's weird that a tune would increase fuel economy so much...
with the frpp tune, do you have to get it done by the dealer? How much does it cost?

I love my 3.73's. just cruising around I shift 1-3-5-6 or 1-2-4-5-6, but when I get on her, I use all gears and she will get up and go with no disappointments. But as far as gas mileage, I have gotten 19 in the city, but to do that you cannot go over 2K RPM, and very slow starts and using overdrive at 40mph (about as slow as you can go in 6th).
Right now I'm averaging about 16 city/highway, but I do get on her quite a bit

I did get it installed through a dealer. I can't 100% remember without looking through my file but it was around $175.

Don't wuss out because of that. The tune is the best first mod. About 75% of the forum runs a non-OE tune. That should tell you something.
