What do stock auto mach's run and what rwhp/tq do they put down, stock. A friend of mine has an 04 auto mach with 4:10'/slp off rd x/pwrflo c-back and jlt ram air. What might he run, I told him low 13's on street tires, and maybe a 12.9 on slicks. I drove it and it's comparable to how my car feels, but his top end feels better.
