Im purchasing an 03 mustang gt A4 with 68,000 miles on it. what are some quick and cheap mods for this car. i owned a 400whp ls1 camaro so im used to having alot of torque.
1. gears (nothing less than 4.10 for the auto)
2. subframes
3. full exhaust (I run a full MAC exhaust and it felt like I picked up 30+rwhp)
4. tune (tune also includes a complete re-mapping of the auto line pressure and shift points)
5. drag radials (with the gears and tranny tune alone, anything less will just spin like crazy)
