Spoke with DeWayne at Logan Motorsports, he has my 4.10 FFRP gear with the part number ending with "A" coming in next week. Going to the track tonight to baseline my new Bamachips tune so I can see what improvement I get with the gears.

 

Good deal!! Post the improements when you find out. I am very seriously interested because I want to go with 4:10's also. Still trying to talk myself into it. My 05 is fast (IMO), the question is do I need it to be faster(quicker)?? I know I would love it but at my age, do I really need them??

 

Yep, you need them. One of the best bang for the buck improvements I made. At your age? You are as old as you let yourself become. 43 and still looking for more power!

 

47 and counting!! But in the stang, feels more like 20ish!!

 

Agreed!![8D]

 

Just remember to break them in first. Don't have them thrown on and head straight to the track.

 

yup, put them through heat cycles to break in, and good luck with em, even though you will be wanting 4.30s in less then a week most liekly

 

How long is the break in? I've had them for the last 4-5 months and I'm really wanting to put mine on reguardless of all the hwy driving I do.

 

2 or 3 trips to the grocery store is enough to break in a new set of FRPPs.

 

how big a difference is the 3.73 to 4.10 in terms of lost gas mpg? Also, does it hurt your top end?
