Would a gear swap warrant a tune?

You guys have me on the fence. I have always said that I want to go 3.73's but I almost thinking 4.10's. The thing thats holding me back is that the car will be my Daily driver for most of the summer months and I really want it to get better gas milage than my truck lol

You will.... I would expect 20-22mpg after gears....

If I remember right K9T8M said that he got 24-25 with his 3.73's. I'd almost have to ride in a car with 4.10's and a car with 3.73's to see if there was a difference

My CVPI came with 3.55's... not interested in changing them....

I have a carrier with 4.30's and a Tlock sitting in my bedroom, I need a few more things to put it in.... carrier bushings, and replace the u joints on my 93 shaft...
