I dont have solid evidence other than you can really feel it. especially with an auto you can set it to shift a tad higher and firmer. 3.73's will only decrease mileage a little bit, it will prolly help your city mpg due to making the engine have to work less, but will decrease the highway mpg a couple. however with an auto you wont be satisfied with 3.73's, i wasn't and had to switch over to 4.10's.

The SCT is a good first choice. It will support your future mods and will be needed to correct the speedometer after gear install anyway. The auto cars get a nice benefit from the reprogrammed shifting characteristics, and if you get a 93 oct tune it will help a little bit. You won't regret starting with the SCT.

Honestly I'd say go with the gears, you'll be lucky to get 10 HP out of a tuner, gears make a night and day difference... The odometer difference really shouldn't concern you, it's not life you're going to suddenly put an extra 10k miles on it...

If he goes with 4.10 gears, which most guys with autos will recommend, his speedometer will read 25.4% high. This means that the speedometer will read 75mph when you are really going only 60mph. For starters, you will have trouble knowing how fast you are really driving due to the screwed up speedometer. Secondly, if you drive the national average of 18,000 miles per year, your odometer will rack up 22,600 miles (or 4600 extra miles) each year. It may not seem like a big deal, but after 100,000 miles, you would show an additional 25,000 miles. It is better to simply plan to get the tuner to correct the speedometer when he installs the gears.
Don't get in the habit of doing things half-a**ed. Best to do it right in the first place.
GOOD LUCK with whatever you decide to do!

I pretty much agree that you would notice a bigger difference with the gears, but you will have to get a tuner sooner or later anyway, so start there and you can adjust your speedometer correctly after the gears.

I agree that gears are the best mod, but if the plan is to get both gears and a tuner in the near future, do the tuner first. The benefits to the auto trans are noticeable and there is NO downside to having the tuner first. Gears first leaves him with a nearly useless speedometer and adds ghost mileage to the odometer.
