Does it hook or spin? Any suspension & tire upgrades?
If I put it to the floor it spins which I like. But I can not go all out and keep it from spinning and it is still faster out of the hole than the 3.31s.
No suspension or tire upgrades yet.

Just picked it up yesterday. I have got about 15 mpg on every tank since I bought it so I will report back.

That's awesome!! I told you that you would love those 4.10s! I'm getting some Kooks LTs put in this spring! Then it's lower control arms and tires! You getting any gear whine at all? With my 4.10s I have not noticed any gas mileage reduction, I'm averaging about 19 mpg with a 93 octane Bama performance tune. Definitely one of the best mods out there! Congrats!!

Glad I listened to you and anyone who suggested 4.10s! No gear whine at all. I think they did a great job with the install other than the panhard bar thing but I don't think that was their fault.
I wish I got 19 MPG! I got 15 when stock, 15 after cold air and tune and don't know yet with the 4.10s. Do you do much highway driving?

Not too much HW driving. I don't drive it real hard, usually just to work and back when it's nice out. It does get off the line much quicker now though! I'm glad you don't have any gear whine, that was the biggest worry I had when I got mine in...

I don't drive it hard that often. But I don't just put around either. Since the 4.10s are in though I seem to get on it more especially going around corners because i like getting a little sideways. LOL! After letting the car warm up for almost an hour yesterday and my spirited driving I am guessing I might get 12 on this tank.

Same here. I love the axle backs too but that was just sound no real hp gain there I'm sure.

Really? I was 28.5 hwy/ 25.5 city stock (3.31s). Even with the supercharger and my 3.73s I still got 25 hwy and then when I put in the 4.10s it dropped to 23 hwy/ 20 city.
Naturaly when I put my foot in it the mileage gets worse
You'll definately want to look at some lower control arms to help control wheel hop and an upper 3rd link to help avoid axle wind with the 4.10s. Ask around about the upper link. I have it swapped out in my car, but I know others who just do the lower control arms and are plenty happy.
I know that I love my 4.10s. I'm glad you like yours too

Maybe I need new plugs or something. And I will look into the lower control arms.

I think that is my main problem. But I don't get on it THAT often.

Well I filled up tonight and got 12.5 mpg. The best I have ever got is 15 and this tank had 2 times of idling for an hour. And I gave multiple rides with lots of WOT runs and did plenty of spirited driving by myself. Going to try and go easy on this tank but the 4.10s make it so fun to drive it is hard.

4.10s are in! Wow. 
Feels like a whole new car now.
