horsepower tips for '00 5.4 F-150

Thanks for the info. and the links 95GTS. The reason I wouldn't want underdrive pullies is because of the experience I've had with my March underdrive pullies for my '90 GT. Underdrive pullies turn both the waterpump & the alternator slower than the stock set up. So when I'm idling in traffic in my F-150 on my daily commute to work...I don't want any charging issues to come up, like dim headlights and slow blinkers. I also don't want to run hot if I have to sit in stop and go traffic for hours on end...pulling my trailer...uphill...etc.
