It wont even be the same car man...i put mine in a few weeks ago. I love 'em. I thought it would hurt my mileage but I think its even better because the engine isn't lugging down the freeway anymore ( i do most of my driving on the freeway). I cruise at about 2200 RPM at 75 mph ( i have 18 inch rims though yours will be higher most likely) and she goes like stink.

So do you have to put the 93 octane gas in it with 3.73's and how do you reprogram the car to read the correct mileage? I know I asked this question a while ago but forgot.

a speedo gears will fix you speedo problem and you should have to run different gas unless you mess with your timing. and as far a break in when i got mine put in the guy said they are either rightor wrong and he races mustangsand hehas done hisfair shareof rearend work

I took my ride out again today for a second day of break in..kind of open her up a bit in the freeway..damn...I'm tellin you guys gears rule. I wish i could have done this first.

Kind of worries me though...my rpms jumps so quick that I'm trying to avoid a red line...lol.. But I guess thats what it's suppose to do.

so no breakin period is necessary? i can turn off the lot and slam it?
