Just got a 2004 mustang gt. It is a 4.6 v8 and it is the 40th anniversary edition so it is automatic. I have put a cold air intake on it already. Basically I'm just wanting to soup it up a bit without having to spend thousands of dollars doing so. So my question is, what are the next steps I should take to improve performance. Any suggestions are appreciated thanks!
355 gears plus drive shaft upgrade. Nice with an auto.
