Most of the ppl who talk bad about 4.10s DONT have them....surprise surprise.

 

but what other supporting mods does he have also re: full exaust,intake ect..ect.. that also has an effect on the mpg. the better the car breaths in and out the more efficent it is and less negitive effects on the mpg. a stock mustang with 4.10's will get worse milage than a full bolt on with 4.10's will.

 

Thanks for all the input guys. I think I will be going with the gears and tuner/software first. I will probably go with 4.10's and was wondering the best all around tuner. I see the general consensus for user interface is sniper? I think that with the gear change and full exhaust and the potential for more bolt-ons down the line. I hear all about sct but I hear that sniper is generally considered a better tuner and has a more user friendly interface. Thanks for all the advice I will be looking at springs/plates and the rest down the line. I am addicted already to this.

 

Sniper FTW
4.10s FTMFW

 

I am going to be buying the 4.10's shortly and was wondering on american muscle they have the rebuild kit and another kit. What is the difference? Do I need both, only one? Just curious and what is the best place to get the sniper tuner? Also, if I do go FI then would I need to upgrade to commando at that point? Again, thanks for all the advice.

 

one kit comes with new bearings, the other just comes with shims n stuff like that. IIRC
