A4 with 3.73's

So...I was thinking of going with 3.73's in my TA. I currently have the stock 3.23's and was wondering how the 3.73's do on the highway at cruising speeds...say 75 mph. I only have a couple mods:

ETP heads
Thunder racing 227XT cam
150 shot of Nitrous
Yank 3600 stall
Trans Go shift kit
full BMR rear suspension

And a bunch of other crap. Anyway, my real question is if the swap to 3.73's are worth it?

1-2mph in the quarter when my car was stocked cubed, H/C.

At 75mph it's going to be around 2700RPM's, I had 3.73's and a SS3600 setup in my Car, it was a pretty good combo.

So for the most part, do you guy's think the swap was worth it?

If you are concerned about E.T. at the track do it..if you are going to install the traction stuff and tires..do it.. if not don't do it.

I only gained .1 in the 1/4 going to a 3.73 gear so I'm not sure how much benefit it actually was but since I was replacing my worn out 10 bolt with a Strange 12 bolt it seemed like the perfect time to try a different gear. My MPG went from 24 to 21 on the highway too.

My friends A4 SS has 3.73s with a stock stall and it feels a lot better than mine. It accelerates a lot quicker at half/full throttle compared to my 3.23s on the freeway....

I say get them they are worth the little be extra get up and go.

I love mine, but I'm on a 28 inch tire. I think I turn around 2200 @ 70 mph.

I have an LT1, but similar set up, Vig 3200 and 3.73s. I had the converter for about 6 years with the stock 3.23 gears, recently got 3.73s, its just a lot more fun to drive with the 3.73s. Well worth it.
