My ex gf bought an 04 Mach 1 and I have an 03 Mach 1.
Hers is an auto. I raced her in my friends 00 SS auto and I pulled a car on her. The SS had catback and lid. Her mach had drop in K&N and off road X pipe with weld in flowmasters. He ran consistent 13.5s
Her car ran much stronger than you would think. I surprised many cars when I raced them.
When I raced her if I gave her the hit and she was able to keep up. That was before my long tubes, PHP spacer, magnapack catback.
Her auto Mach seemed like a freak. Never got to dyno and when we broke up she went back to Florida so not sure what it ran or power numbers.
