'07 5.4 UD Pulleys
Anyone out there install UD pulleys on a stock 5.4?
Does the alternator still put out the necessary voltage and keep the same battery life? I have a short 15 minute commute to work.
Does it really make any noticeable difference in either feel or mpg?
How much $ does it cost? Just the crank pulley gets changed?
Are all brands the same?
If you add a VMP tuner, are the benefits cumulative?
