who has 3.73's or 3.90's in there GT?
Wondering what you guys thought on these ratios. I have an '07 GT 5spd. I dont want it to be a radical change, but enough to notice the diference. Is not a drag car and is driven daily. I run constant 13.7-13.8 with street tires and S&B Intake (no tune). would like to run 13.4-13.5's.
What would make more diference? Getting a tune? or gears? I will aventually do both.... which shall I do 1st?
Thanks for you guys input.

Put 3.90 in about a month before I installed my cai and tune. pulls much harder than the 3.31 that came orig equip. My RPM at 80 mph is about 2700 and I am running an auto

a good freind of mine ran 12.7 at 106 with the following:
jlt2 intake
predator tune
upr off road x
drag radials
so if you get the tune and a off road x you should be low 13s no prob.

I heard the newer GT's with off road X/H pipes. Man Its too loud for me. I have the 40 series Flowmasters and thats as loud as I will go. I'm just debating between gears or tune...which should I do 1st?

i have 3.73's and it was quite a bit difference...depends on how much driving you do daily...i drive 60 miles one way on the highway daily so gas would rape me if i had higher gears. if little to no driving, go with the 3.90's or even 4.10's

I wish 3.90s wern't so prone to whining. I'd run those seeing how I do so much hwy driving. The 4.10s aren't horrible on the hwy, but if I take my stang to europe next year I may have to put 3.73s in or find a viper spec T-56 for the hwys there, if you not doing 120, your crawling. I'm opting for the T-56, so I guess I'll be holding rabbits for ransom.
