Was wondering:

1) Who has had this done?

2) How much did it cost you?

3) How much of an increase did you see?

4) Oh, and did you see any gas mileage drop?

Thanks guys!

alot of people at the mustang collective have that kinda work done, these forums draw in more GT owners

there are 103,000 posts in the GT section and

23,000 posts in the v6 section.

Not trying to be an advertisement for that site because i have 1,000+ posts on this site and under 100 on that one but when it comes to v6 performance that forum will have answers.
