I run 93 in my 06 5.4L anyway. Its not that much more over 89, so I always get 93. its only a few $1's a fill up.
93 is normally $0.20 higher, that means $4.00 per 20 gallons. A whopping $4.
S/C depends on the person, come like centri, some like roots.
Personally, I think if you are that worried about going fast, and adding power buy a cheep sports car.
For what a S/C costs for these trucks I can go buy a Z28 right now, loaded out.
I hate to say it, but simple truth is the LT engine platform makes far more power far cheaper than most ford engines will. IMO

If i change the rear end gears will i have to change the front also?
exhaust i'm not to sure of because i don't want it to be loud bc it is a family vehicle and we take long trips with her...
thanks for the help! I was just seeing if anyone had a huge improvement for the 5.4 that didn't bust the bank account too bad. i guess what im saying is what would be my best bet for a good increase across the motor. something that i could really feel!

Get a programmer along with custom tunes and stay away from that canned crap......
If you get a SCT Xcal3 it will be able to grow with your truck as you do mods especially a supercharger.

higher grade fuel is a given, so yes.

I have an 04 supercrew lariat with the 3.73 axle and 4X4. I currently only have an CAI and throttle body spacer. I want to get better performance and towing out of my truck but it HAS to be RELIABLE. I looked into the superchargers but people don't recommend them for towing... so i looked at the sts turbo and people say its a vacuum for water. Plus the price for either one of them is more than i would like to spend.
I just want to get the most bang for my buck. Let me know what you guys are doing to make your 5.4's perform better.

2 months ago (August 18) installed whipple SC. Dynotuned and Tremendous torque increase. Now hauls trailer without a problem. Not sure why you were told different.(expect $8-9k out the shop door)
