Ok I got a 2000 v6 mustang with Mac long tube headers, Mac H-pipe & dual 40s on it. Also a Predator Diablo Tuner on it and CAI.
They say a 2000 v6 mustang runs a 16 to 15 mid in the 1/4 mile stock correct? Any ideas on these mods on which it would run in the 1/4 mile? I want to add Underdrive pulleys and 4.10s on it soon. Anyone know of the track times with these mods on there cars?

 

I don't think they will get you out of the 15's, but the 4:10's might.
