Logan,
I'm ready to change the gears on my MM03. I went to Houston Performance yesterday (a Mustang specialist). I told them I wanted 4.10's. They where a little concerned that it would mess up my shift points and my speedo.
Heres what I want to do,
4.10's
thermostat
Plugs
Reinhart chip.
Apart from picking up the rev's a little, and the HP alot, what else can I expect to see ?.
They wanted about $400 to change the gears ( Motorcraft) does that sound right ?.
