Just want to know which of this is better..
rear end gears and performance chip or..
UDP, rear end and lightweight flywheel.
Im not sure about the UDP because I have a RF amp and two 10" subs.
might probably hav a problem with the alternator.
I have 2000 v6 stang with MAC shorty headers, H-pipe and dual exhaust. and k&n CAI..
( after installing rear end, does anyone knows what gonna be my top end?)
thanks guys...
