ok so i just signed up for this so i dont really know much about the site but i have 3 mustangs as of now one is a 1969 coupe that i am restoring the second is a 91 which i am selling and the other is a 2000 gt. the 00gt i just got a few weeks ago and im impressed it has a cold air intkake, gears, a diablo chip, x pipe exhaust, and semi slick rear tires. the car is fast but i still want more horse power lol. so if anyone has any suggestions of a cheap way to increase horse power let me know...i was thinking about a new throttle body and possibly headers. thanx.

Welcome to the forum.
You might try asking the guys in the 4.6 section.
I am familiar with 5.0

 

Welcome to the forums! We have some great tech sections where you can ask questions about restoring or modding the newer stang.
