Hey guys, finally joined the "gear group" haha. I had some FRPP 3.73s installed and honestly...I was expecting more. I notice a ok gain in transfered power, but maybe I was expecting a bigger jump. I haven't really "driven" the car until the first 100 miles are over with. After that, i'll chime in and see what I think.

Also, I had a friend of mine drive next to me and it seems that my speedo is reading 5 mph faster than what I am going. Will a tuner or a new speedo gear fix that problem?

are u manual or auto?

shoulda gone 4.10s or maybe even 4.30s (auto)

I own an Auto. I would have loved to go 4.10s, but rather keep my rpms low during highway speeds. Plus I plan on supercharging it later down the road.

Maybe a NICE tune will help my situation out, huh?

Yes a tuner will allow you to fix the speedo. Even with you getting a s/c down the road, 4.10s would have been better and you would have noticed more of a difference. Either way 3.73 is better than the stock gears.

+1...the 4.10's would not be too much gear at all, even with a blower. My buddy has 3.73's in his 5-speed Procharged 01 gt, and wishes he went with 4.10's.

the difference between 3.73s and 4.10s MIGHT be 1mpg.

and its harder to feel in an auto.

shoulda went 4.10s. I regret selling mine, i might have to go buy a new set if im not happy.

Supercharged as well.

The procharger takes a little bit to spool up giving the 4.10s time to shine down low. If it was a roots type or another quick spooling blower, i dont think you would enjoy them without some fine tires.

man i went with 3.73s in my 96 gt manual, and to be honest im kinda disappointed, i was gonna go with 3.90s, but since im getting the heads, cams and blower installed i went with 3.73s, but if i was to keep it stock 4.10s all the way in my opinion,,,

but automatic 4.10s, 4.10s, 4.10s is the way to go

but hey its better then before

Yeah, im new to the mustang game and that was one of the first thing people told me, go 4.10 gears if you get an auto. Just be happy it feels better....
