Ok so i just ordered borla stinger catbacks, stack racing cai, and a sf3 sct tuner and am wondering what to put next on the list. Want to go with and intake and plenum combo but i also really want to get a set of gears. Can anyone offer up any advice? Thanks

 

Gears will give you the best seat of the pants dyno bang for the buck than anything. Go for 3.73's if you have a 5 speed and 4:10's if you have an auto. Or you can go middle ground like I did and go for 3:90's

 

How do those 3.90's feel?

 

Almost just like a 4:10 but I have more top end grunt

 

Rlly 3.90's give you more top end?

 

More top end than a 4:10 but less than a 3:73

 

Unless you plan to autocross or really really care about gas mileage I like the 4.10s

I went from 3.31 to 4.10 and I could never go with less in this Mustang.

 

Ok yea i think im just gonna go with 4.10's. Have to order exhaust, cai, and tuner on tuesday so maybe with the tuner my mpg's wont be affected by 4.10 gears.
